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.
