This CL adds a check to the `Is` castable methods to determine if the
target type is `final`. If the type being compared too is `final` we
bail out early in the walk up the hierarchy as it won't be a parent
class.

Add a 'NodeID' to each ast::Node which is the sequentially allocated
index of the node. Use this in sem::Info to map the AST node to the
semantic node, instead of using a std::unordered_map.
Optimised very hot code by entirely eliminating map lookups, and
dramatically reducing cache misses (lookups are usually sequentually
ordered).

Any AST expression may map to a sem::Materialize, so the inferred

return nullptr).

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.

When enabling the SPIR-V reader or SPIR-V writer we were suppressing
-Wnewline-eof, -Wold-style-cast, -Wsign-conversion, and -Wweak-vtables
for the `libtint` cmake target and anything that depended on that
target. Because we'd build all readers/ writers by default this caused
us to never hit those warnings.
A recent change to the cmake build sets the Tint backend based on
the Dawn backend. So, there is a much higher chance of not building
the SPIR-V support if you're on a Mac or Windows machine.
This CL removes the suppression of the warnings, adds specific pragmas
into the SPIR-V reader code which imports the SPIRV-Tools headers
and fixes up the warnings which were then firing due to checking
for the new warnings.

Instead of vector-of-variant.
This:
• Makes it impossible to produce a mix of scalar variant types, which
would make no sense.
• Reduces the size of a Constant, by removing the union-tag from each
element.
Also clean up terminology. Rename 'Constant::Scalar' to
'Constant::Element'. Scalars are well-defined in WGSL, and with the
introduction of abstract-numerics, this no longer makes sense.

With abstract materialization, any ast::Expression may map to the new
sem::Materialize node. Because of this, we can't assume that an
ast::CallExpression maps to a sem::Call, as it might be wrapped by a
sem::Materialize.
Remove the mapping, and fix up all the code that was relying on this.
Fixes are done by either:
• Calling `UnwrapMaterialize()->As<sem::Call>()` on the semantic
expression. This is done when the logic may assume it's possible for
the expression to be a Materialize node.
• Using the explicit sem::Info::Get<sem::Call>() template argument to
cast the semantic type to sem::Call. This is done when the logic
either knows it is impossible for the expression to be a Materialize.
The backends have been stubbed, as we'll want to emit the constant value
for these nodes. It's likely that we'll just use the FoldConstants
transform to strip all Materialize nodes from the tree. For now, be
defensive.

Migrate from a hand-rolled tagged-union of [i32, u32, f32, f16, bool]
types. Instead use a std::variant of [AInt, AFloat, bool]. The Constant
holds the actual type, so no information is lost with the reduced types.
Note: Currently integer constants are still limited to 32-bits in size.
This is enforced by the frontend.
