This moves the usage of Tint in the fuzzers into a single class. This
will be expanded in the future to support emitting shaders, so fuzzing
tests, just need to indicate which reader & writer they want to use,
instead of having each test implement all of the API usage logic
directly.

Demangle the printed AST before comparing.
Many to_str() methods on AST nodes will print the symbol numerical identifiers, which is not guaranteed to be stable between clones.
By comparing the demangled AST, these should be stable.

Remove the logic around `arrayLength()` being passed anything but a member accessor. Runtime arrays types cannot be used for variables nor parameters.
Add validator logic and test for runtime array parameters.
Adjust the validator error message so it doesn't include the field / variable name. This read weird, and the same information is already provided by the source.

The interface for cloning a module was made significantly more complex in https://dawn-review.googlesource.com/c/tint/+/35502/ as some of the transforms required constructing symbols before the clone. This was temporary solution in 35502 was to copy the symbol table, then construct the new types, then perform the clone. This lead to a really messy callback interface, that was extremely error prone (e.g. lamda-capturing stack variables from the initializer callback that had been unwound).
Instead, clone the symbols as they're encountered. This may produce an entirely different set of identifiers, but no longer ever-grows the symbol list, and keeps the interface clean.
