Revert of Fix memory leak caused by field type in descriptor array.

Reason for revert:
Breaks test/mjsunit/debug-clearbreakpointgroup.js on arm64.debug.

Fix memory leak caused by field type in descriptor array.
When a field type is a map, it is wrapped in a weak cell upon storing to
the descriptor array.
Map::GetFieldType(i) does the unwrapping.
