Add the fixed-rate compression ratios exposed by GL and Vulkan to the
flags for gbm_bo and gbm_surface creation, and intersect these with the
list of supplied modifiers to add another filter.
Although gbm_surface could support this by the EGLSurface flags in
EGL_EXT_surface_compression, gbm_bo cannot: it allocates a buffer first
and then imports it into the consuming API post-hoc, after the modifier
is already (must be) known. It seems more important to keep the
gbm_surface and gbm_bo APIs in sync, so keep the responsibility for
filtering on the GBM side.

Commit introduces a fix that allows for gbm to be built with an empty
backend. There are situation especially in a Yocto/OE cross compilation
environment where you want to build with an empty backend. The particular
situation is as such:
The mesa-gl recipe is the preferred provider for virtual/libgbm, virtual/libgl,
virtual/mesa, etc... But the x11 DISTRO_FEATURE in't included this leads to build
errors such as:
| /../../../ld: src/gbm/libgbm.so.1.0.0.p/main_backend.c.o: in function `find_backend':

undefined reference to `gbm_dri_backend'

Issue should be replicable by setting -Ddri3=disabled and -Dgbm=enabled

Older drivers will not expect any flags from the
GBM front-end when modifiers are in use, and will
likely fail the allocation or handle them
incorrectly as a result. Only specify usage flags
when allocating from a backend with an ABI >= 1,
as that's the ABI version that added support for
specifying usage flags along with modifiers.

Android.mk files haven't really been supported by Mesa devs for a long
time. Most of us have been willing to update Makefile.sources if we
remember and sometimes we try to blind code some Android.mk for a new
generator. However, the reality is that it breaks regularly and ends up
being maintained by the Android community. To address this problem
another approach was implemented in !10183 utilizing the maintained
meson build system. The old Android.mk files are no longer required.
This commit was created with the following commands:
git rm **/Android.mk

A subsequent change will allow loading backends
from DSOs specified by the GBM_BACKEND environment
variable. The exact DSO name and path are derived
by the common loader code and will be of the form:
<gbm_backend_path>/<GBM_BACKEND>_gbm.so
E.g., a user would set the environment variable to
"external" to load "external_gbm.so". Users will
also still be able to explicitly request any
builtin backends by name as well, so this change
helps keep the environment variable syntax
consistent between internal and external backends.

Define a version number for the interface GBM uses
to offload work to its backends/drivers. Store the
version in the backend interface structs provided
to the loader by backends, as well as in the core
interface struct provided to backends by the GBM
loader code to backends.
The backend can create structures of any version
it supports, which can be greater or less than the
interface version specified by GBM in the core
interface structure. Hence, GBM will need to take
care to check the backend version before accessing
any members added to structs defined in
gbm_backend_abi.h after this change.
Similarly, the backend may need to check the
interface version supported by the GBM library
before passing back data in any structure members
that require the GBM library to interact with
them for correct operation. For example, if for
some reason a structure defined in
gbm_backend_abi.h gained a field which was a
pointer to memory allocated by the backend and
freed by GBM, the backend should avoid allocating
this memory if the GBM library did not specify an
interface version new enough to indicate that it
was aware of the new structure member.
