31aa3d6019 SPV: only declare the pure 8/16-bit capabilities when needed.
Only when operations stray outside the 8/16-bit storage-capabilities
are the general (pure 8/16-bit) capabilities needed.

312dcfb070 Implement GL_EXT_shader_16bit_storage and GL_EXT_shader_8bit_storage extensions.
These introduce limited support for 8/16-bit types such that they can only be accessed in buffer memory and converted to/from 32-bit types.

Contributed from Khronos-internal work.
