initializers being only const-expr is no longer done by the

This enables the WGSL parsing of 'const' for only tint_unittests,
allowing code to be split up into smaller chunks for review.
Once all the logic is submitted to handle 'const', the test-only
flag will be removed, and 'const' will be enabled for production.

Motivation is to simplify cache evicting by reusing the LRU to evict stale entries from older Dawn versions since there isn't already a simple cache busting solution. The dawn version will just be pushed into the cache keys instead so old version entries will eventually be retired.
- Removes the fingerprint from the GetCachingInterface API on DawnNative.
- Adds the "fingerprint", which was just the hash, to the device;s cache key directly instead.

And remove the WrapArraysInStructs transform.
Wrapping arrays in structures becomes troublesome for `const` arrays, as
currently WGSL does not allow `const` structures.
MSL 2.0+ has a builtin array<> helper, but we're targetting MSL 1.2, so
we have to emit our own. Fortunately, it can be done with a few lines of
templated code.
This produces significantly cleaner output.

Use a common pattern of sanitizing, building and dumping the whole
module instead of calling individual methods. There's too much internal
state being tracked in the tests for my liking.
Split most tests into three:
* Const_* tests will check the emission of creation-time-constant
expressions.
* Runtime_* tests will check the emission of runtime expressions, where
indexing operates with a constant index.
* Dynamic_* tests will check the emission of runtime expressions, where
indexing operates with a runtime index.
