This also fixes an issue where we were taking the stringified diagnostic list and creating a single error on resolution failure. This was the cause of the `error: error:` messages sometimes seen.

lets us more easily verify that the test shaders are valid in the first

- Add test/extract-spvasm.py to split that output to separate SPIR-V
assembly files
- Add optional second argument test/test-all.sh to specify a directory
look for input files.
- BUILD.gn: Add dependency from //test:tint_unittests_main to

Resolver creates semantic types from the AST types. Most downstream
logic continues to use the semantic types, however transforms will now
need to rebuild AST type information instead of reassigning semantic

The spirv parser now creates ast types along with sem types via
typ::Type. All sem::Type* were replaced with typ::Type, and its `ast`
member is used over the `sem` member to make it easier to migrate to
ast-only.
The parser was written to take advantage of the fact that types were
resolved to semantic types during parsing. For instance, a mapping of
spirv typeid to sem::Type* was used throughout (`id_to_type_`) to
resolve types once, and to support type aliasing. Since the goal is to
only create AST types, and to resolve only in the Resolver, I made many
changes to remove this dependency on semantic types. For instance, we
now always call ConvertType(typeid) instead of looking up via
id_to_type. Similarly, the `signed_type_for_` and `unsigned_type_for_`
maps were replaced with `UnsignedTypeFor` and `SignedTypeFor` functions.
