Add command line argument to switch gpu backend. Add `--gpu-backend` option to
override the gpu backend selected by Blender.
Values for this option that will be available in releases for now are:
* opengl: Force blender to select OpenGL backend.
During development and depending on compile options additional values can exist:
* metal: Force Blender to select Metal backend.
When this option isn't provided the internal logic for GPU backend selection will be used.
Note that this is at the time of writing the same as always selecting the opengl backend.

MTLContext provides functionality for command encoding, binding management and graphics device management. MTLImmediate provides simple draw enablement with dynamically encoded data. These draws utilise temporary scratch buffer memory to provide minimal bandwidth overhead during workload submission.
This patch also contains empty placeholders for MTLBatch and MTLDrawList to enable testing of first pixels on-screen without failure.
The Metal API also requires access to the GHOST_Context to ensure the same pre-initialized Metal GPU device is used by the viewport. Given the explicit nature of Metal, explicit control is also needed over presentation, to ensure correct work scheduling and rendering pipeline state.

This cleans up the OpenGL build flags and linking.
It additionally also removes some dead code.
One of these dead code paths is WITH_X11_ALPHA which actually never was
active even with the build flag on. The call to use this was never
called because the default initializer for GHOST was set to have it off
per default. Nothing called this function with a boolean value to enable it.
These cleanups are needed to support true headless OpenGL rendering.
Without these cleanups libepoxy will fail to load the correct OpenGL
Libraries as we have already linked them to the blender binary.

With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.
This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.
libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.

The `ascii` member was only kept for historic reason as some platforms
didn't support utf8 when it was first introduced.
Remove the `ascii` struct members since many checks used this as a
fall-back for utf8_buf not being set which isn't needed.
There are a few cases where it's convenient to access the ASCII value
of an event (or nil) so a function has been added to do that.
*Details*
- WM_event_utf8_to_ascii() has been added for the few cases an events
ASCII value needs to be accessed, this just avoids having to do
multi-byte character checks in-line.
- RNA Event.ascii remains, using utf8_buf[0] for single byte characters.
- GHOST_TEventKeyData.ascii has been removed.
- To avoid regressions non-ASCII Latin1 characters from GHOST are
converted into multi-byte UTF8, when building X11 without
XInput & X_HAVE_UTF8_STRING it seems like could still occur.

This reverts commit 086f191169.
There was apparently a problem using APPEND which wasn't referenced
in the commit log.
Added comment noting the reason for the discrepancy.
This was already done for APPLE & WIN32, which would
reference these libraries twice.
Now append BROTLI_LIBRARIES to FREETYPE_LIBRARIES when they're
required for linking.
No functional changes as all references to FREETYPE_LIBRARIES also
used BROTLI_LIBRARIES.
The UI team requested adding woff2 support to freetype.
this required a new dependency brotli.
This changes adds brotili to the builder and bumps
freetype to version 2.11.0
As freetype now depends on other libraries, for consistency
all use of ${FREETYPE_LIBRARY} in cmake has been updated to
use ${FREETYPE_LIBRARIES} adjustments have been made in the
windows platform file, all other platforms use cmake's
FindFreeType.cmake which already sets this variable.

There is no need to have another font embedded in the Blender executable, we
can assume the bundled font exists. In the future we may provide a fallback
if the font specified by the user in the preferences is missing a character,

Developers should add non license comments as separate comment blocks.
No need for separator text.
