Unlike on Windows, where command line argument splitting is done by the
callee, on 'nix systems, the arguments need to be split by the caller.
Fixes issues where validation was different on windows to other
operating systems.

* 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.

Change tint's `--fxc` flag to take the path of the FXC compiler DLL.
Have tint attempt to validate with both FXC and DXC if `--validate` is
passed.
Fix the 'dirsWithNoPassExpectations' logic which looks like it got
broken with the tint -> dawn merge. It also incorrectly applied
filepath.FromSlash() on windows.

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.

Concatenating strings to use for cache keys is horribly inefficent and very error prone.
Add a UnorderedKeyWrapper helper to allow types to be used as a unordered_map and unordered_set key. Use this for the type_constructor_to_id_ map.
Produces SPIR-V with some duplicate SPIR-V instructions for constructors removed.

Add a Hash() and Equals() methods to sem::Type.
Have sem::Manager (which should be called sem::TypeManager) derive from
utils::UniqueAllocator. This now uses the Hash() and Equals() for uniquely
constructing semantic types instead of building strings and comparing those.
