Reland "Partial revert of aosp/2858589 to avoid Mesa layer for Android"

This reverts commit 9eef6d0aefcf0aa1c07d42d9b307b1092a6deec9.

... as this does not yet have a way to generically convert Mesa
handles into Gfxstream handles in extension structs which causes
breakage in dEQP VK for many tests.

Moves the mesa based codegen to a separate `mesa_func_table`.

Reland fixes the end2end test guest vulkan ICD.
