[wasm] Rework CALL_INTERFACE macros in WasmDecoder

Main change: Remove CALL_INTERFACE macro. Use
CALL_INTERFACE_IF_REACHABLE or invoke interface directly instead.
Reasoning: Interfaces assume the Decoder is in a non-error state,
therefore CALL_INTERFACE invoked DCHECK(this->ok()). However,
CALL_INTERFACE (1) was sometimes erroneously called with an error in the
decoder, especially in cases where the error occurred inside immediate
argument parsing, (2) was always called in contexts where the current
control was guaranteed to be reachable. Due to (1) and (2),
CALL_INTERFACE is equivalent to CALL_INTERFACE_IF_REACHABLE (there are
a few exceptions where we can call the interface directly).

Additional change:
- Rename current_code_reachable_ to current_code_reachable_and_ok_
  to make its name reflect its meaning better.
