Produce a warning if the attribute is missing for integral vertex
outputs or fragment inputs. This will become an error in the future,
as per the WGSL spec.
Add the attribute to E2E tests.

We previously rejected nested structures for entry point IO only if
there was an attribute on the member in the outer struct. This change
rejects all nested structures instead.

TypeDecls (alias, structure) are not a types - they declare types.
ast::TypeName is what's used for a ast::Type.
Previously we were trying to automatically convert these to TypeNames in the builder, but having these inherit from ast::Type was extremely error prone.
reader/spirv was actually constructing ast::Structs and using them as types, which is invalid.

Required a lot of test fixes.
ProgramBuilder: :ConstructValueFilledWith() was a major source of unreached AST types, and this has been removed with more powerful type-building helpers in resolver_test_helper.h.

Checks the following things:
- Non-struct entry point parameters must have pipeline IO attributes
- Non-struct entry point return type must have a pipeline IO attribute
- Structs used as entry point parameters and return values much have
pipeline IO attributes on every member
- Structs used as entry point parameters and return values cannot have
runtime array or nested struct members
- Multiple pipeline IO attributes on a parameter, return type, or
struct member is not allowed
- Any given builtin and location attribute can only appear once for
the return type, and across all parameters
Removed tests for nested structs from the SPIR-V transform/backend.
Fixed a couple of other tests with missing pipeline IO attributes.
