[3.12] gh-119821: Support non-dict globals in LOAD_FROM_DICT_OR_GLOBALS (#119822) (#119890)

The implementation basically copies LOAD_GLOBAL. Possibly it could be deduplicated,
but that seems like it may get hairy since the two operations have different operands.

This is important to fix in 3.14 for PEP 649, but it's a bug in earlier versions too,
and we should backport to 3.13 and 3.12 if possible.
