Bump the github-actions group across 1 directory with 2 updates

Bumps the github-actions group with 2 updates in the / directory: actions/github-script and taiki-e/install-action....

Always ensure room in rb_obj_embedded_size

Although the issue only occurred on debug builds, we should always be
requesting a size large enough to fit the object when it expands to the
heap, rather than just hoping the GC provides enough room.

ZJIT: Make hir::types::Class not final and have it include metaclasses

Every class boots with a metaclass, and all metaclasses are subclasses
of Class, so types::Class has no business in ExactBitsAndClass.
In fact, we should never see an object whose RBasic::class is exactly...

Remove extra sentinel from shape capacities

This isn't a 0 terminated list anymore because we iterate over
heaps_count directly. So we don't need to allocate an extra byte for the
sentinel

Make it obvious that field count guard is for debug

This is because when RVALUE_OVERHEAD is positive, ie. when
RACTOR_CHECK_MODE is enabled and we need to store the pointer to the
owning ractor, we need to make sure there is enough space to store it....

Replace sweeping_heaps map with a counter

We implemented some bit twiddling logic with an unsigned int to have a
neat way of tracking which heaps were currently sweeping, but we
actually don't need to care which heap is sweeping right now, just
whether some are or not, so we can replace this with a counter.

Use the pre-processor to generate slot sizes and reciprocals
