Hoist out parsing module from spirv_cross::Compiler.

This is a large refactor which splits out the SPIR-V parser from
Compiler and moves it into its more appropriately named Parser module.

The Parser is responsible for building a ParsedIR structure which is
then consumed by one or more compilers.

Compiler can take a ParsedIR by value or move reference. This should
allow for optimal case for both multiple compilations and single
compilation scenarios.
