This change implements pointers and references as described by the WGSL
specification change in https://github.com/gpuweb/gpuweb/pull/1569.
reader/spirv:
* Now emits address-of `&expr` and indirection `*expr` operators as
needed.
* As an identifier may now resolve to a pointer or reference type
depending on whether the declaration is a `var`, `let` or
parameter, `Function::identifier_values_` has been changed from
an ID set to an ID -> Type* map.
resolver:
* Now correctly resolves all expressions to either a value type,
reference type or pointer type.
* Validates pointer / reference rules on assignment, `var` and `let`
construction, and usage.
* Handles the address-of and indirection operators.
* No longer does any implicit loads of pointer types.
* Storage class validation is still TODO (crbug.com/tint/809)
writer/spirv:
* Correctly handles variables and expressions of pointer and
reference types, emitting OpLoads where necessary.
test:
* Lots of new test cases

The expected output is far from perfect, and the generated HLSL and MSL
isn't even validated yet, so may be incorrect.
However, by committing the generated output, we get clear examples of
the currently generated output of each backend. As we land fixes and
improvements to each backend, the presubmits will require us to update
the expected test output, and so code reviews will include diffs of
each backend's generated output.

Makes future development easier.
New features:
* A more compact and cleaner results view
* Concurrent testing, much quicker across multiple cores
* Supports comparing output against an expected file, including a text diff of differences. Also has a flag for updating the expected outputs
* Advanced file-globbing support, including scanning for files in subdirectories
* Skip lists are now no longer hidden away in the tool, but defined as a SKIP header in the *.expected.* file

In preparation for implementing
https://github.com/gpuweb/gpuweb/issues/1604, this change removes the
sem::AccessControl node. Instead, the ast::AccessControl::Access enum is
now on the sem::StorageTexture class, as well as on sem::Variable. For
sem::Variable, the field is set when the variable's type is either a
storage buffer or a storage texture.

This change also removes Resolver::Canonical(), which is now unneeded as there are no sem::Aliases to remove.

There's now no need to have both.
Removes a whole bunch of Sem().Get() smell, and simplifies the resolver.
Also fixes a long-standing issue where an array with an explicit, but equal-to-implicit-stride attribute would result in a different type to an array without the decoration.

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

- Move headers from libtint_sem_src into libtint_core_all_src so that
there is no circular header dependency between headers of these two
targets. libtint_sem_src is now just a hack to have a different name for
a few .cc files.
- Made libtint_core_src publicly depend on its deps so that headers of
libtint_core_all_src are made visible through it.
- Added spvtools dependencies in a couple places that were mistakenly
removed in a previous commit.
- Moved helpers common to multiple unittest targets out of
tint_unittests_core_src and into a tint_test_helpers target that
all tint_unittests_source_set depend on.
- Ran GN format that reordered some lists a bit.

This makes the .cc files match the header file name, which allows for
the text editor "header flip" feature to actually work. The reason these
files were named this way was because GN doesn't allow name conflicts in
the same source set, despite the files being in different directories.
This change splits the files into different source sets. To do so, we
use GN templates, which also reduces duplication in each target
definition.

The MSL writer GTest harness (TestHelper) now provides a function to
invoke the XCode SDK Metal compiler for the MSL output of a given
tint::Program.
The tint_unittests binary now provides the `--validate-msl` and
`--xcrun-path` command-line flags to optionally enable MSL validation
and to configure its path.
The MSL validation logic itself is conditionally compiled based on the
TINT_BUILD_MSL_WRITER define. The TINT_BUILD_* flags were previously
not propagated to the GTest binary which this CL addresses by linking
the common/public tint configs when building the tint_unittests_main
target.

Registering a new Symbol with the NameFor() of the source symbol creates
a new *named* symbol. When mixing these with unnamed symbols we can have
collisions.
Update CloneContext::Clone(Symbol) to properly clone unnamed symbols.
Update (most) the transforms to ctx.Clone() the symbols instead of
registering the names directly.
Fix up the tests where the symbol IDs have changed.
Note: We can still have symbol collisions if a program is authored with
identifiers like 'tint_symbol_3'. This will be fixed up in a later
change.
