[wasm] Fix some WASM comments and outputs

In text, we should use the properly capitalized "Wasm" instead of
"WASM". In particular for frame output, other frames typically use
CamelCase (like "JsToWasmFrame", "ExitFrame", "InternalFrame"), so Wasm
should do the same.
The "0xa" comment in some assemblers is also outdated, the current tag
we emit for StackFrame::WASM is 0x8 (0x4 shifted by one).
