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.

If there is a continuing block we pull the variables declared in the
loop up into the scope outside the loop. This allows those variables to
be used in the continuing block.
We pull out all variables instead of detecting ones which are only used
in continuing as that's easier and still correct.
