Nothing uses these, and the mutability of these breaks
const-correctness.
Switch functions that used to return `const utils::Vector<T, N>&`
to returning `utils::VectorRef<T>`. Removes the templated size from the

Replace all `const utils::VectorRef<T>&` with `utils::Vector<T>`,

This CL moves the ArrayCount from a variant to use inheritance. This
will allow the sem to have different array count classes from the IR.
The ArrayCounts, similar to types, are unique across the code base and
are provided by the TypeManager.

Currently the TypeManger is a UniqueAllocator. This works as long as the
TypeManager only manages one specific thing. In order to support
ArrayCount, which is type related, but not a type, the TypeManager will
need to be able to store two types of things.
This CL changes the TypeManager to contain a UniqueAllocator and proxies
the needed Get, Find and iteration methods to that allocator. This will
allow another allocator to be added for ArrayCount later.

Previously Hashmap used to internally use a Hashset which held entries
of key-value pairs. This was cute, but meant that a Hashset held mutable
entries, which was a bag-of-bugs waiting to happen (change the entry to
hash as something different and you're now in an entirely broken state).
Pull the complex bits of Hashset out to HashmapBase, and have both
derive from that. I've opted for inheritance over composition here to
reduce the amount of structure chasing you'd have to do without
debugger pretty-printers.

This uses template and macro magic to reflect the fields of a class.
Dawn:
* Reflect the fields of the types that are used by Dawn's stream::Stream<T> specializations, and use tint::ForeachField() to call StreamIn().
Fuzzers:
* Replace tint::fuzzers::DataBuilder::BuildImpl<T> specializations with the new reflection system.
* static_assert that the type is either POD or reflected. Add a specialization for std::optional which was missing.
Move tint::transform::BindingPoints into MultiplanarExternalTexture, as this is only used by MultiplanarExternalTexture.
All this reduces fragility of the struct declarations slipping out of sync with the uses.

* Added a class template argument deduction guide (CTAD) to infer the
`T` and `N` template arguments. This lets you write `Vector{1,2,3}`
instead of `Vector<int, 3>{1,2,3}`. This is important as a mismatch
between the number of constructor arguments and the `N` template
argument can cause silent heap allocations, which we're trying to
avoid. The `T` deduction uses the same smarts as the return-type
deduction of `Switch()`, so:
* `Vector{1, 2.0}` would construct a `Vector<double, 2>`
* `Vector{i32, u32}` would construct a `Vector<const sem::Type*, 2>`
* Removed the Vector(size_t) and Vector(size_t, const T&) constructors.
This is a move away from the std::vector style API, but these are
rarely more efficient than calling Reserve() and Push(), as you remove
the redundant initialization. The main reason for doing this is to
remove ambiguity between `Vector{1}` and `Vector(1)`.
* Added support for covariance conversion
(`Vector<Derived*, N>` -> `Vector<Base*, N>`).
Only supports pointers to `Castable`, as this can only safely work
with single-inheritance.
* Added support for conversion of `Vector<T*, N>` -> `Vector<const T*, N>`.
This will remove pointless vector copies from the sem package.

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.
