gfxstream: add meson build

Right now, gfxstream downloads dependencies it needs via CMake
`FetchContent`, and that's generally in-advisable when writing
a package for distribution.

The CMake build also exports libraries and symbols that ideally
should be kept internal to gfxstream (like opengles.cpp symbols).
This is due to AEMU CMake compatibility, but even upstream
QEMU has moved to a meson based system. Meson should work well
on Unix systems, and Windows the standard strategy is to use a
mingw cross-compiler.

This allows gfxstream to be a completely external and versioned
dependency.

Note, tests were not compiled and only Linux has been tested so
far.  Also, meson configure -Ddecoders=auto is recommended until
decoder specific code can be further isolated.

BUG=284306280
TEST=Compile using the following options:

(Linux dependencies)
sudo apt-get install libdrm
sudo apt-get install libglm-dev
sudo apt-get install libstb-dev

mkdir aemu-build
(in platform/hardware/google/aemu)
cmake -DAEMU_COMMON_GEN_PKGCONFIG=ON -DAEMU_COMMON_BUILD_CONFIG=gfxstream
      -DENABLE_VKCEREAL_TESTS=OFF . ../
make -j && sudo make install

(in gfxstream)
mkdir amd64-build
meson -Ddefault_library=static amd64-build/
ninja -C amd64-build
sudo ninja -C amd64-build/ install
