HeapObject::SizeFromMap() was too large to get inlined anyway. HeapObject::IsFoo() predicates should be implemented in foo-inl.h, because that's what they depend on. This patch also fixes up includes: dropping unnecessary ones from object-inl.h, and adding them in other places that previously relied on getting them transitively.

When creating the results object for an exec call, V8 is calling into a runtime helper once per named capture group. It can instead create that object without any runtime calls, using existing CSA helpers. The only additional cost of this approach is that it internalizes the capture group names at regex compilation time, even if the script never calls exec on that regex.

This cl: https://chromium-review.googlesource.com/c/v8/v8/+/1421077 changed the implementation of SetProperty to infer the language mode. Language mode is only required when there is an error to decide if we have to throw an error or not. However we used to compute language mode eagerly for PropertyCallbackInfo. This causes regressions in some benchmarks. This cl changes it by deferring it further by computing it only when it is actually required.
