Fixes a problem with the inlining of JS-to-Wasm call wrappers into a
surrounding exception handler and re-enables this case.

Modify the cctests for the inlined JS-to-Wasm calls to use the
%ObserveNode intrinsic, to verify that the JSCall node is actually
inlined . This requires a small refactoring of the %ObserveNode
implementation.

This is a reland of 6ada6a90ee
- Fixed a GC issue
https://bugs.chromium.org/p/v8/issues/detail?id=11335:
GC expected all arguments on the stack from code with
CodeKind::TURBOFAN to be tagged objects. This is not the case now with
inlined Wasm calls, and this information can be passed in
SafepointEntry for each call site.
- Disabled JS-to-Wasm inlining for calls inside try/catch.

This replaces https://chromium-review.googlesource.com/c/v8/v8/+/2376165/.
Currently JS-to-Wasm calls go through a wrapper/trampoline, built on
the basis of the signature of a Wasm function to call, and whose task
is to:
- set "thread_in_wasm_flag" to true
- convert the arguments from tagged types into Wasm native types
- calculate the address of the Wasm function to call and call it
- convert back the result from Wasm native types into tagged types
- reset "thread_in_wasm_flag" to false.
This CL tries to improve the performance of JS-to-Wasm calls by
inlining the code of the JS-to-Wasm wrappers in the call site.
It introduces a new IR operand, JSWasmCall, which replaces JSCall for
this kind of calls. A 'JSWasmCall' node is associated to
WasmCallParameters, which contain information about the signature of
the Wasm function to call.
WasmWrapperGraphBuilder::BuildJSToWasmWrapper is modified to avoid generating code to convert the types for the arguments
of the Wasm function, when the conversion is not necessary.
The actual inlining of the graph generated for this wrapper happens in
the simplified-lowering phase.
A new builtin, JSToWasmLazyDeoptContinuation, is introduced to manage
lazy deoptimizations that can happen if the Wasm function callee calls
back some JS code that invalidates the compiled JS caller function.
