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.

This function was attempting to pick a higher-precision type by using
the decltype() of FROM + TO. This doesn't work if FROM and TO are both
similar bit-widths, and of a different signness, as the picked type may
not be wide enough to hold both the signed and unsigned representation.
Just use AInt or AFloat (both 64-bit), which are the largest types
supported by WGSL.

And remove the WrapArraysInStructs transform.
Wrapping arrays in structures becomes troublesome for `const` arrays, as
currently WGSL does not allow `const` structures.
MSL 2.0+ has a builtin array<> helper, but we're targetting MSL 1.2, so
we have to emit our own. Fortunately, it can be done with a few lines of
templated code.
This produces significantly cleaner output.

Split most tests into three:
* Const_* tests will check the emission of creation-time-constant
expressions.
* Runtime_* tests will check the emission of runtime expressions, where
indexing operates with a constant index.
* Dynamic_* tests will check the emission of runtime expressions, where
indexing operates with a runtime index.
