The Metal programming language is a C++14-based Specification with
extensions and restrictions.
Tint is written in C++14.
Take advantage of the fact that MSL is based on the same language that
Tint is written in, and validate that the field members match what the
C++ compiler expects.

Implement layout logic for vectors, matrices and default-stride arrays.
Custom stride arrays are complex, and will be tackled as a followup change.
This change also emits byte offsets for all structure members as comments. This is even emitted for non-storage uses, which can be cleaned up as a followup.
Fixes a whole lot of TINT_ICE() for non-complex WGSL shaders.

Added enforcement for vector constructor type rules according to the

This surfaced a number of existing tests that violated some of these
rules or had a type-declaration related bug, so this CL fixes those as
well (these tests either passed the incorrect number of arguments to a
vector constructor or relied on implicit conversions between numeric
types).
