This PR implements a register context for Wasm, which uses virtual registers to resolve Wasm local, globals and stack values. The registers are used to implement support for `DW_OP_WASM_location` in the DWARF expression evaluator (#151010). This also adds a more comprehensive test, showing that we can use this to show local variables.
