Variables in the storage storage class and variables with a storage
texture type must have an access attribute applied to the store type.
https://gpuweb.github.io/gpuweb/wgsl/#module-scope-variables
A variable in the storage storage class is a storage buffer variable. Its
store type must be a host-shareable structure type with block attribute,
satisfying the storage class constraints.
Fixup tests, including those that were producing warnings about `var <in>`
The WGSL writer seems to want to put a newline after every decoration block, leading to some ugly output. I'll fix this as a separate change.

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.

In this situation the parser may try to reparse the same token, forever.
By calling sync_to() we either find the end of the block, and forward progress can be made, or synchronized_ is set to false, and the parser can error out cleanly.
