HeapHandle is an opaque handle that refers to the internal
implementation of the heap and as such should never be used by value.

The CL is a prerequisite for the shared cage. Instead of storing
state variables (is_incremental_marking_in_progress,
is_young_generation_enabled) in the cage metadata, the CL moves them to
HeapHandle. The HeapHandle pointer is now retrieved from page-headers.
To make sure that the write-barrier code is better optimized, the
HeapHandle definition is moved to internal/ headers. The part of
BasePage that contains HeapBase (i.e. HeapHandle) pointer is also
extracted and moved to the headers.
