This allows building Mesa with the Android NDK, which doesn't provide
libdrm.
We will generate an `Android.bp` file using the `ninja-to-soong` tool
(https://github.com/rjodinchr/ninja-to-soong), and to do this we run
Mesa's standard meson build system to generate the ninja commands that
we then translate to soong.
That meson invocation is done using the Android NDK, which doesn't
provide libdrm, so until we find an alternative solution[*] we provide a
wrap file that builds libdrm as part of the Mesa build (but does not
install it--we still use the Android-provided libdrm at runtime)

there comes a time when a project has to be declared unfit to remain
in the tree
this frontend hasn't seen actual development in about 6 years
if someone has a pressing need to continue development, there's no
blocker to un-deleting it, but unless that happens, there's now a
more featureful, more conformant, more active CL frontend in the tree

The extra `all_free` that now remains in the list will be ignored in the
loop below anyway so there is no need to have complex code to try to
remove it.
This also means it becomes possible to set things like
`-D video-codecs=all_free,vc1dec`.

as previously discussed.
this is using "library CL" instead of kernel CL, which is the older way of doing
things. it works, it just has more boilerplate per-kernel than we'd want
otherwise. but library CL is basically free to integrate into a driver, whereas
kernel CL requires a lot more upfront investment. (I'm working on cleaning that
up but we're not quite there yet.)

In theory you can build a driver using OpenCL kernels with a
-Dmesa-clc=system. That shouldn't require any LLVM/Clang/etc...
But the checks to find the pre-compiled mesa_clc & vtn_bindgen
binaries are in meson files or conditions only triggered if you build
with LLVM (:

This Vulkan layer allows reporting a limited VRAM size to the
application. This layer can be useful for testing applications and
games which query for the memory budget adjusting their behavior
accordingly.
They layer does not set a hard limit on the amount of VRAM thus
applications can still make allocations even though the reported
budget might indicate no memory is left, if the set limit is lower
than of actually available VRAM.

Native context support is implemented by diverting the libdrm_amdgpu functions
into new functions that use virtio-gpu.
VA allocations are done directly in the guest, using newly exposed libdrm_amdgpu
helpers (retrieved through dlopen/dlsym).
Guest <-> Host roundtrips can be expensive so we try to avoid them as much as
possible. When possible we also don't wait for the host reply in case where
it's not needed to get correct result.
Implicit sync works because virtio-gpu commands are submitted in order to the
host (there a single queue per device, shared by all the guest processes).
virtio-gpu also only supports one context per file description (but multiple
file descriptions per process) while amdgpu only allows one fd per process,
but multiple contexts per fd. This causes synchronization problems, because
virtio-gpu drops all sync primitive if they belong to the same fd/context/ring:
ie the amdgpu_ctx can't be expressed in virtio-gpu terms.
For now the solution is to only allocate a single amdgpu_ctx per application.
Contrary to radeonsi/radv, amdgpu_virtio can use libdrm_amdgpu directly: the
ones that don't rely on ioctl() are safe to use here.

Initial "compilable" version of mesa/gfxstream on Windows. For now it is
achieved through "#if !DETECT_OS_WINDOWS" directives hence it is NOT
functional. The compilation works with mingw only and the compilation is
tested in a windows host. This commit is intended to only pass the
compilation process without errors.
Also created stub code for a future windows implementation.

"python3" should still be preferred because sometimes "python" is python
