[win32] Apply Operation pattern on GC

This commit provides a minimal implementation to apply the operation
pattern on GC that is used on most other resources to re-create
resources
on zoom changes. A difference in this implementation is that there is
always exactly one OS handle per GC. On zoom change the existing handle
is cleaned up a created for the new zoom. There is no use case that
requires managing of multiple handles per GC.
