and rename WasmFrame to WasmCompiledFrame.
The WasmToInterpreterFrames are not used yet; this will follow in a
follow-up CL (see tracking bug for the overall picture).
Those frames will represent frames for WASM_TO_INTERPRETER stubs, which
call from wasm code to the wasm interpreter, implemented in C++.
They will support the Summarize method to inspect the stack frames in
the wasm interpreter.
