James Price 11c6fcdb51 spirv: Use generic transform to process shader IO
The refactored CanonicalizeEntryPointIO transform makes it much easier
to handle SPIR-V style IO as well, and doing this removes a lot of
duplicated code. Remove all of the SPIR-V transform code for shader IO
and vertex point size.

James Price d18f2e0d6e writer/spirv: Do not add Flat to fragment outputs
Use the sanitizer to add the decoration only to the variables that are
vertex outputs and fragment inputs.

James Price 5ea0fe00bf writer/spirv: Add Flat decoration to integers
Vulkan requires that shader inputs/outputs that are integers must be
decorated with Flat.

James Price bb0496e52a test: Add E2E test coverage for shader IO
This provides much more complete coverage than what we have in the
unit tests. We now test:
- All builtins, for all stages, both struct and non-struct
- Multiple location attributes for vertex and fragment stages, both
  struct and non-struct
- Mixing builtins and location attributes, whilst mixing struct and
  non-struct
- A few "interesting" cases of IO structs being shared between
  different functions, stages, and with an SSBO variable

There are 7 skipped tests for MSL due to two different MSL bugs which
will be fixed in upcoming patches.
