      cppgc: shared-cage: Remove heap-specific metadata from cage-header · 62159ea3
      Anton Bikineev authored
      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.
