spirv-as: Avoid overflow when parsing exponents on hex floats (#4874) 
* spirv-as: Avoid overflow when parsing exponents on hex floats

When an exponent is so large that it would overflow the int
type in the parser, saturate the exponent.
This allows extremely large exponents, and saturates
to infinity when the exponent is positive, and zero when the exponent
is negative.

Fixes #4721.

* Avoid unexpected narrowing conversions from arithmetic operations
