The --dump-spirv option tells tint_unittests to output the
SPIR-V assembly text for a module which did not make the SPIR-V reader
fail. This lets us get extract a corpus of SPIR-V modules, and
lets us more easily verify that the test shaders are valid in the first
place.
Also:
- 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
//test:tint_unittests_config to pick up source dependency on
the internal header of the SPIRV-Tools optimizer, needed by
the indirection through src/reader/spirv/parser_impl_test_helper.h
This is useful for bulk testing

Remove all sem::Type references from the AST.
ConstructedTypes are now all AST types.
The parsers will still create semantic types, but these are now disjoint
and ignored.
The parsers will be updated with future changes to stop creating these
semantic types.
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
information, as semantic nodes are fully rebuilt by the Resolver.

typ::Types originating from ConvertType() will hold direct pointers to ast::Struct and ast::Aliase. These must not be used directly. Instead TypeNames should be created to refer to these.

My last CL (https://dawn-review.googlesource.com/c/tint/+/49542) made it
so that AST nodes are re-created every type we resolve a spirv type id
to a tint type. This creates duplicate nodes, most of which are cleaned
up at the end of parsing. However, duplicates added as global
constructed types are not handled, so this CL makes sure we do not add
said duplicates.

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.

The HLSL writer doesn't really care much for ast::Types, so most of the work here is repointing the logic to fetch the resolved, semantic type.
Output for aliases has changed, as the semantic type resolves away aliases.

Instead of printf-ing and returning an empty string.
When there's a lot of other test output, it can be really hard to actually spot the error message.
With the error being returned, this will likely appear in a EXPECT_EQ() style error message.

This takes precedence over semantic types.
WGSL should be printed as faithfully as possible to the parsed program.
The semantic nodes are more abstract than the AST - aliases are folded
away, decorations may be absorbed into the semantic types, etc.
