UI: Label Fixes

These were added in rB146473f08335e8cb774ccaf1baad82a1d308fbe1 however
there were a few errors with the labels:

1. Underscore in label
2. Abbreviation when not needed

Fix: Blender_test not working on windows.

This bumps the minimum requirement for cmake from 3.10 to 3.18 on windows
if `WITH_GTESTS` is enabled.

Fix T79278: Selected object filter skipping collection instances

Collection instance datablocks were not filtered out when only showing
the selected object. They were treated as a collection (which should
show when filtering objects). Adds a case to check if the parent is an
object.

Add compound shape for rigid body simulation

This patch adds a new compound shape entry to the shape selection
dropdown. It also corrects wrong inertia calculation for convex hulls,
that resulted in strange behavior for small objects.

The compound shape take the collision shapes from its object children
and combines them. This makes it possible to create concave shapes from
primitive shapes. Using this instead of the mesh collision shape is
often many times faster.

Enable header auto-complete suggestions in Xcode

Description of `USER_HEADER_SEARCH_PATHS` build setting:
"
This is a list of paths to folders to be searched by the compiler
for included or imported user header files (those headers listed
in quotes) when compiling C, Objective-C, C++, or Objective-C++.
Paths are delimited by whitespace, so any paths with spaces in
them need to be properly quoted. See Always Search User Paths
(Deprecated) (ALWAYS_SEARCH_USER_PATHS) for more details
on how this setting is used. If the compiler doesn't support the
concept of user headers, then the search paths are prepended to
the any existing header search paths defined in Header Search
Paths (HEADER_SEARCH_PATHS).
"

http://help.apple.com/xcode/mac/current/#/itcaec37c2a6

Xcode doesn't use `HEADER_SEARCH_PATHS` for auto-complete. Only the
header files in the same directory as the current file are suggested.

CMake as of now correctly sets `SYSTEM_HEADER_SEARCH_PATHS` and lumps the
rest in `HEADER_SEARCH_PATHS`. The standard way is to use
`USER_HEADER_SEARCH_PATHS` & `SYSTEM_HEADER_SEARCH_PATHS` and let
`HEADER_SEARCH_PATHS` be used as a fallback for compilers which do not
distinguish between `<*.h>` and `"*.h"` syntax.

So set `USER_HEADER_SEARCH_PATHS` to the include paths specified
in the `CMakeLists.txt` files of all targets.

Fix T79357: VSE crash on prefetching when performing cuts

Caused by {rBa1a333a1e92e}

`BKE_sequencer_prefetch_get_original_sequence` cant get a sequence in
`BKE_sequencer_cache_put`.

rBa1a333a1e92e moved multiple NULL checks (including the one checking
seq) above BKE_sequencer_prefetch_get_original_sequence (this should
never return NULL really, but this is for another fix).

So solution suggested by @ISS is to just stop prefetching all together
before changing content of seqbase.

Sculpt: Use constraints in cloth deform brushes

Previously, deform brushes were modifying the final positions in the
simulation directly, which was causing all sorts of artifacts in the
deformed area and problems with other features of the solver.
Now these brushes deform a separate array of positions and the solver
adds constraints to them, so the real vertices are moved when solving
the constraints. This prevents those artifacts and gives the brush a
much better behavior.

Sculpt: Enable persistent base for the cloth brush

The cloth brush builds the constraints when the stroke starts usign the
current state of the mesh. This means that deformations profuced by the
simulattion will accumulate after multiple strokes as it will always
start from the previous deformed state. While this is useful in many
cases, for other uses it is convenient to always simulate the same
initial shape, but applying different forces to it.

The persistent base options work like the persistent base in the layer
brush and allows the cloth brush to not accumulate deformation after
each stroke. When enabled, constraints are created for the shape stored
in the persistent base instead of from the current state of the mesh.
