Property Search: Properly set expansion for instanced panels

Stack panels (for modifiers, etc..) also get their expansion from their
associated list data. This means that property search expansion needs
to properly update the list data, which can be accomplished by calling
`set_panels_list_data_expand_flag`.

This commit also moves this logic to `UI_panels_end`, where it fits
better.

ASan/macOS: fix incomplete C/CXX compiler flags.

While testing for {rB40dcf686f04f}, compiler flags got mixed up and
non-working ASan configuration was committed.

Platform file, which is `include`d after the `CMAKE_C_FLAGS_DEBUG` etc.,
are set, overwrites those flags instead of appending to them. To fix this,
`PLATFORM_CFLAGS` is used to pass the `-fsanitize=*` flags to the C/C++
compiler.

Tested on fresh build using both Xcode and Ninja, with & without ccache.

Also silence a clang warning for multi-config generators:
the object size sanitizer has no effect at -O0, but is explicitly
enabled: -fsanitize=object-size [-Winvalid-command-line-argument]

GMP/macOS: silence "PIE disabled" linker warning.

The change builds GMP with `--with-pic` flag on non-arm architecture.

The warning:
ld: warning: PIE disabled. Absolute addressing
(perhaps -mdynamic-no-pic) not allowed in code signed PIE, but used in
___gmpn_divexact_1 from lib/darwin/gmp/lib/libgmp.a(dive_1.o). To fix
this warning, don't compile with -mdynamic-no-pic or link with
-Wl,-no_pie

UI: Refactor some list panel expansion code

This commit moves the "get panel expansion from list data" function to
UI_panels_end, which is an improvement because it's more centralized.

Deps: Add potrace as a new library dependency

For work the GP team plans to land soon (T79877) potrace was taken
on as an additional optional dependency.

This diff adds building the library to the deps builder and takes
care of the integration into the build-system with the `WITH_POTRACE`
cmake switch.

Outliner: Hierarchy line drawing

Adds a new hierarchy line that draws to the left of collections. If the
collection is color tagged, then the hierarchy line is drawn in that
color. This is useful to see the color tag of a collection that exceeds
the vertical height of the outliner when expanded.

This also modifies the object hierarchy line drawing to match the new
collection hierarchy line, with no horizontal lines, and moved a unit to
the left. Object lines are not drawn colored.

Collections: Add color tagging

This adds color tagging to collections. There are 8 color
options which are themable in the user preferences, with an additional
option for no color tag by default.

This adds a new filled collection icon and 8 colored variants of the
icon that can be themed in the user preferences.

In this commit the only interface to setting the color tags is through
Python, and there is nowhere in the interface where the collections are
shown colored. Setting and viewing the color tags from the outliner will
follow.

Liquid Simulation Display Options (GSoC 2020)

All the changes made in the branch `soc-2020-fluid-tools` are included in this patch.

**Major changes:**

=== Viewport Display ===

- An option to display //gridlines// when the slicing method is //single//.

==== Grid Display ====

- Visualization for flags, pressure and level-set representation grids with a fixed color coding based on Manta GUI.

==== Vector Display ====

- //**M**arker **A**nd **C**ell// grid visualization options for vector grids like velocity or external forces.
- Made vector display options available for external forces.

==== Coloring options for //gridlines// ====

- Range highlighting and cell filtering options for displaying the simulation grid data more precisely.
- Color gridlines with flags.

- Also, made slicing and interpolation options available for Volume Object.

Property Search: Quick start and clear operators

`ctrl-F` to start the search is obviously necessary, but the clear
operator, `alt-F` requires some of explanation. First, it maps nicely
to the paradigm of "key to set, alt-key to clear," which makes it
unobtrusive. Second, it can be a quicker way to clear the search than
moving the mouse to the top. Finally, in the future, it could a reset
the panels to their expansion before the search started.

UI: Single tab property search

This adds a search bar to the properties editor. The full search for
every tab isn't included in this patch, but the interaction with
panels, searching behavior, UI, region level, and DNA changes are
included here.

The block-level search works by iterating over the block's button
groups and checking whether they match the search. If they do, they
are tagged with a flag, and the block's panel is tagged too. For
every update (text edit), the panel's expansion is set to whether
the panel has a result or not. The search also checks for matching
strings inside enums and in panel labels.

One complication to this that isn't immediately apparent is that
closed panel's subpanels have to be searched too. This adds some
complexity to the area-level panel layout code.

Possible Future Improvements:
- Use the new fuzzy search in BLI
- Reset panels to their expansion before the search started if
the user escape out of the text box.
- Open all child panels of a panel with expansion.

Dont show temporary IK constraints in the constraint stack

Those constraints are added when using AutoIK (or targetless IK as
well).
While not strictly incorrect, these kinds of constraints were not
showing in the UI prior to rBeaa44afe703e (and I think they should not).

Property Search: Move properties context buttons back to a panel

The context path "breadcrumbs" used to be in a panel in 2.79.
Although they look a bit better in the header, there isn't enough
space for them with the property search field in the header as well.

Maybe there will be another solution in the long term to fit both
the search field and this panel in the header, but for now, this
commit moves these labels back to a header-less panel.

Property Search: Build button groups for Search

This is needed for property search (upcoming patch D8856) where a
buttons labels are often separate buttons, but we need to highlight
the label to show that a property is a search result. This is
especially important in "property split" layouts where the label is
almost always another button in a separate column.

The button groups here are basically a flattened view of the buttons
in the layout tree. Every function that adds a new set of buttons
creates a new button group, and the new buttons are automatically
added to the most recent group. Then, each group is searched
separately in the property search phase. It's important that every
function adding a new button set calls layout_root_new_button_group.

Note that this won't be disabled when property search isn't active.
It may be useful for other things in the future, and trying to pass
that information to layout functions didn't feel worth it to me.
