Added Pass and PassQueue to Spirit

Bug: 30964317

Reorganized rs2spirv using PassQueue.

Changed LiteralString from const char * to std::string, so that the
life cycle of the underneath string is correctly managed.

Improved Transformer so that it can capture changes made to the
global or decoration section while transforming function defintions.

Fixed #include order per LLVM coding convention.

Test: unit tests, lit tests, and RSoVTest
