Clemens Backes 61c2a0f4ba [wasm] Remove interpreter entry code 
This removes the interpreter entry stubs, which are used to redirect
specific wasm functions to the interpreter. It is only needed when
mixing JS code with interpreted Wasm code, otherwise the test functions
just call the interpreter directly.
Thus a lot of tests that contain such interaction between JS and Wasm
need to be restricted to execute in Liftoff and TurboFan only.

After this CL, the WASM_INTERPRETER_ENTRY frame type and the
corresponding WasmInterpreterEntryFrame are dead, and will be removed in
a follow-up CL.
