This supports pattern listener events in the BodyBuilder without
crashing. Currently no AST is created and only dummy objects are put
on the stack.

Since none of the subparts of the base method share any local state,
make the base method virtual and override it in all of the subclasses
with the subclass-specific functionality.
Also add an `ASSERT(IsNull());` check to all base implementations to
cause an error in DEBUG mode when forgetting to override in a subclass,
and then perform what should happen in the null case (if anything).
This way, in DEBUG mode, it's easier to distinguish an accidental null
slipping through vs. a lack of overriding.
TEST=Pure refactoring, so existing tests.

The Crash class was used for to conflicting purposes: 1) To encapsulate
a captured crash in the CFE, in which case the trace was printed
directly, and 2) To propagate a crash in the CFE together with the
context in which it crash, in which case the trace was not printed but
just included in the Crash object.
This CL adds a `_hasBeenReported` field to ensure that 1) is rethrown
as intended and 2) is printed and a Crash object of type 1) is returned.

Fix: Check handle contents for Smi.
Closes: https://github.com/flutter/flutter/issues/112726
Orignal CL description:
Makes `Dart_Handle` FFI returns behave as the following snippet:
```
Dart_Handle ExampleSnippet() {
Dart_Handle result = ...;
if (Dart_IsError(result)) {
Dart_PropagateError(result);
}
return result;
}
```
Also makes FFI consistent with Dart_NativeFunctions, which will
automatically throw upon return if Dart_SetReturnValue set the result
to an error.
`UnhandledExceptions` cannot flow out into Dart generated code. So,
the implementation needs to be in `FfiCallInstr::EmitNativeCode`.
Using `Dart_IsError` is slow compared to a machine code class id
check. So, we should do the handle unwrapping and class id check in
machine code.
Unwrapping Handles in machine code is only safe when the GC is
guaranteed to not run: Either (1) in `kThreadInGenerated`, or (2) in
`kThreadInNative`, but only when transitioned into safepoint. So, the
handle cannot be unwrapped immediately after the FFI call in machine code. We first need to transition back to generated.
This means we need to transition again to native to do the actual
`Dart_PropagateError` call. We can do so without the stub in JIT
because we never return with normal control flow.
Performance impact of this change is within benchmark noise in both
JIT and AOT.
Size impact is 42 bytes on x64, which is 10% in AOT and 12% in JIT.
