e68d4506c0 tint/resolver: Consistently use utils::Result in ConstEval
Instead of using builder.Diagnostics().contains_errors()

Produces cleaner code and reduces scope of error handling.

c2a052eaa4 tint: Allow ConstEval functions to fail

34d46731bb tint: Replace VectorRef with ConstVectorRef.
The elements of the VectorRef is now immutable, but can be
moved, if the caller relinquishes ownership by explicitly using
std::move() at the callsite.

Also add utils::Empty as a way of signalling that a vector should be
constructed with no elements. This is helpful in templated code where
{} cannot be used due to overload ambiguity.

6a80ce6c66 tint/resolver: Use the intrinsic table for type const dispatch

Removes more bloat from Resolver, and creates a centralized class for

aa037ac489 tint: Refactor sem::Constant to be less memory-hungry
Change sem::Constant to be an interface to the constant data. Implement
this so that zero-initialized data doesn't need to allocate the full
size of the type.

This also makes usage a lot cleaner (no more flattened-list of
elements!), and gives us a clear path for supporting constant
structures if/when we want to support them.
