Fix UnboundMethod#== for methods from included/extended modules [Backport #21873]
Method#unbind clones the method entry, preserving its defined_class.
For methods mixed in via include/extend, defined_class is an ICLASS,
causing UnboundMethod#== to return false when comparing against the
same method obtained via Module#instance_method.
Resolve ICLASS defined_class in method_eq.

objspace_dump: Skip invalid CME when dumping CCs
When a CC is invalidated only the klass field is set to 0. After it's
invalidated it isn't safe to access the CME, as it may have been freed.
I made a similar change in Ruby 4.0 in
640a2f1dc77c0ecf226dbd71cf7a1eb876a1f037, but assumed it was due to the
changes we'd made to callcaches making klass a weak-reference.

[3.4] Fix deadlock on th->interrupt_lock after fork
[Bug #21860]
If a thread was holding this lock before fork, it will not exist in the
child process. We should re-initialize these locks as we do with the VM
locks when forking.

[PATCH] Don't force major GC when there are allocatable slots
[Bug #21838]
When we have allocatable slots, we can grow the heap instead of forcing
a major GC. This prevents major GC to be ran very often in certain situations.
See the ticket for more details.
On ruby-bench, we can see that this patch doesn't cause any significant
regressions:

[PATCH] search_nonascii(): Replace UB pointer cast with memcpy
Casting a pointer to create an unaligned one is undefined behavior in C

Practically, this yields the same binary output in many situations
while fixing the crash in [Bug #21715].
