This removes the obsolete support to create {WASM_COMPILED} stack frames
within the out-of-line trap handler code. All trapping code needs to
push such a frame on entry by now, because the instance object is pushed
implicitly as part of the prologue. Deferred frame building would not
have access to a valid instance object.
