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 ===

- //Raw voxel display// or //closest (nearest-neighbor)// interpolation for displaying the underlying voxel data of the simulation grids more clearly.
- 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).

Fix T80333: cursor disappears after using navigation gizmo in editmode

Caused by rBe490dc4346db: UI: Skip unnecessary cursor setting

Above commit returned early if the cursor was already set, but did this
before visibility was regained, now return (still early) after setting
visibility.

Tests: bundle tests for some modules in their own executables

The ffmpeg, guardedalloc and blenlib are quite isolated and putting them in
their own executable separate from blender_test is faster for development than
linking the entire blender_tests executable.

For Cycles, this also bundles all the unit tests into one executable.

I also considered going back to having every test file in its own executable,
but the size of these executables does add up quickly, and linking and running
all blenlib tests is still < 1s here.

CMake: clean up setting of platform specific linker flags

Set flags directly on the target, and use common function for all cases.

Property Search: Add "search match" theme color

We will use a highlight on panel headers to convey that they have
a search match, so this commit initializes the theme color for the
properties editor.

GPencil: Define default destructor

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.

GPencil: Fix compiler warnings

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.

Cleanup: Remove unneeded parameter

A parameter was added during development, but it was not needed and was
never removed. No functional changes.

Fix T80787: Fix White edges when rendering transparent smoke

The UV/Image editor was doing interpolation including over the alpha
value what makes will render incorrectly when interpolating between pure
emissive colors and pre multiplied colors. This change disabled the
interpolation.

UI: Add `icon_only` argument to operator_enum

Add an option to only draw icons for operator_enum menus. This is used
for drawing inline icon buttons in the outliner context menu for
collection color tagging.
