Andreas Kling 75e7bc1e2a LibJS: Move source range cache from ExecutionContext to Executable ...

CachedSourceRange was a GC-allocated cell stored on the
ExecutionContext, only needed because ExecutionContext must be
trivially destructible.

Move the source range cache to a HashMap<u32, SourceRange> on the
Executable (keyed by program counter), where it belongs. This
eliminates the GC::Cell subclass entirely and removes the
cached_source_range field from ExecutionContext.

StackTraceElement and TracebackFrame now store Optional<SourceRange>
directly instead of GC::Ptr<CachedSourceRange>.

Shrinks ExecutionContext from 144 to 136 bytes.
