Unlike error strings, diagnostics can:
* Describe more than one error
* Be printed with colors
* Highlight (`^^^`) the particular error on the line
* Can have separate severities

Migrate all uses to use this and the new `unique_type<T>()` and `types()` methods.
Remove the `type_mgr()` accessor. `TypeManager` is now an implementation detail of the module, allowing us to unify the allocation of types and nodes (if we so wish).

Add `tint::writer::FloatToString()`:
Converts the float `f` to a string using fixed-point notation (not scientific).
The float will be printed with the full precision required to describe the float.
All trailing `0`s will be omitted after the last non-zero fractional number,
unless the fractional is zero, in which case the number will end with `.0`.
Use this for the wgsl, msl and hlsl backends.

This CL updates the binary operator emission to use the `mul()` method
in the following cases:
- vector * matrix
- matrix * vector
- matrix * matrix
This is because the `*` operator works per-component in HLSL which does
not do the expected multiply.

The reason being that some tests called parse() twice, which will silently destruct the first parser.
Once the `Module` owns the AST nodes, the second call will end up deleting all the AST nodes. Tests would then perform use-after-free for the AST nodes belonging to the first parser / module.
There's no reason why the unique_ptr can't be returned, which is cleaner overall.
