anv: Autogenerate extension query and lookup

As time goes on, extension advertising is going to get more complex.
Today, we either implement an extension or we don't.  However, in the
future, whether or not we advertise an extension will depend on kernel
or hardware features.  This commit introduces a python codegen framework
that generates the anv_EnumerateFooExtensionProperties functions as well
as a pair of anv_foo_extension_supported functions for querying for the
support of a given extension string.  Each extension has an "enable"
predicate that is any valid C expression.  For device extensions, the
physical device is available as "device" so the expression could be
something such as "device->has_kernel_feature".  For instance
extensions, the only option is VK_USE_PLATFORM defines.

This mechanism also means that we have a single one-line-per-entry table
for all extension declarations instead of the two tables we had in
anv_device.c and the one we had in anv_entrypoints_gen.py.  The Python
code is smart and uses the XML to determine whether an extension is an
instance extension or device extension.

gles: Restore some lost typedefs

GLES/gl.h has historically provided some typedefs that are not
used in the API itself. Restore these typedefs that were lost to
avoid breaking applications.

These seem to be the only typedefs removed in the update.
