Add the change in tint behavior to the OT notes.
Add end to end tests for underscores. While the GLSL and MSL compilers seem to accept leading and double underscores in identifiers, the tint build failure has highlighted we have more work to do here (crbug.com/tint/1319)

Since CMake 3.21, the Ninja generator now outputs absolute paths to
source files, rather than relative. These paths are what __FILE__ gets
mapped to during compilation, and is what gtest outputs for test
failures. This broke fix-tests, which assumed a build-relative source
path. This change detects when the source file path is absolute, and
converts it to a build-relative one.
Also, on Windows, absolute paths include the drive with a colon
character, so I added matching the colon to the regex for the path
portion.

And remove a whole load of const_cast hackery.
Semantic nodes may contain internally mutable fields (although only ever modified during resolving), so these are always passed by `const` pointer.
While all AST nodes are internally immutable, we have decided that pointers to AST nodes should also be marked `const`, for consistency.
There's still a collection of const_cast calls in the Resolver. These will be fixed up in a later change.

Handle access control on var declarations instead of via [[access]]
decorations. This change does the minimal work to migrate the WGSL
parser over to the new syntax. Additional changes will be needed
to correctly generate defaulted access qualifiers, as well as
validating access usage.
The [[access]] decorations are still supported by the WGSL parser,
with new deprecated warnings, but not for aliases. Example:
var x : [[access(x)]] alias_to_struct;
Making this work is far more effort than I want to dedicate to backwards
compatibility, and I do not beleive any real-world usage will be doing
this.
Still TODO:
* Adding access control as the optional, third parameter to ptr<>.
* Calculating default accesses for the various storage types.
* Validating usage of variables against the different accesses.
