[tint][msl] ArgBufs: emit `_ =` statements unambiguously

Without argbufs, a `_ =` of a uniform/storage value results in:

  uint3((*tint_module_vars.f));

However, with argbufs, `f` becomes a function argument resulting in:

  uint3((*f));

  program_source:30:10: error: pointer type must have explicit address
  space qualifier

This is supposed to be an `expression;` but in C++ it gets parsed
incorrectly as a variable declaration, like `uint3* f;`.
Add parentheses around the expression so it can't be parsed that way:

  (uint3((*f)));

Note, this doesn't happen with bare constructor calls (see call.wgsl)
because in that case phony assignments get emitted for example as:

  int3 const v_2 = int3(z, z, z);

That would work here too, but would require changes to the IR that's
generated for (at least) this particular case, where a constructor is
generated to convert packed_uint3 to uint3. It seems more complicated to
make sure that fully covers all cases, whereas just inserting
parentheses here is simple.

Tests updated with:
  ./tools/run fix-tests out/r/tint_unittests
  ./tools/run tests --tint out/r/tint --generate-expected
