The benchmarks contain some duplicated code, but we want to avoid
starting to measure indirection and the compiler not inlining in
these benchmarks, so it's better to keep them as plain as possible.

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.

This CL adds FFI leaf calls by adding `lookupFunction(.., isLeaf)`
and `_asFunctionInternal(.., isLeaf)`, which generate FFI leaf calls.
These calls skip a lot of the usual frame building and generated <->
native transition overhead.
`benchmark/FfiCall/` shows a 1.1x - 4.3x speed-up between the regular
FFI calls and their leaf call counterparts (JIT, x64, release).
TEST=Adds `tests/ffi{,_2}/vmspecific_leaf_call_test.dart`. Tested FFI tests.

This CL does not yet roll `package:ffi` to use `Allocator`, because that
breaks the checked in Dart in Flutter in g3. Instead, this copies
`_CallocAllocator` from `package:ffi` into the benchmarks. (We need a
copy per benchmark such that file-copying before running benchmarks
works properly.) The copies can be deleted when we can update
`package:ffi` in the DEPS file to contain `_CallocAllocator`.
