Update dependencies for addition of set.h to public headers

Add Set C-API

This should be a minimal C-API needed to deal with Set objects. It
supports creating the sets, checking whether an element is the set,
adding and removing elements, iterating over the elements, clearing
a set, and returning the size of the set....

Rename some set_* functions to set_table_*

These functions conflict with the planned C-API functions. Since they
deal with the underlying set_table pointers and not Set instances,
this seems like a more accurate name as well.

Lookbehind regexp must be fixed-length

Fixes [Bug #21507]

ZJIT: A64: Have add/sub to SP be single-instruction

Previously a missed optimization for add followed by mov. While we're
at it, have Add and Sub share the same match arm in arm64_split().

Fix heap-use-after-free in rb_getaddrinfo (#13856)

This change addresses the following ASAN error:

Remove accidentally committed method Module.gccct_clear_table

This was probably meant to be only for debugging. It was introduced in
the big namespace on read commit: 382645d440d

ZJIT: Print a message about ZJIT_RB_BUG when unused (#13852)

Fix rb_eSystemExit raised in Ractor

[Bug #21505]

Previously Ractor.new { exit }.join would hang because SystemExit was
special cased.

This commit updates this to take the same path as other exceptions,
which wraps the exception in a Ractor::RemoteError and does not end up...

ZJIT: Mark Snapshot as having an output

Other instructions use it as an operand and #13814 especially needs it
to have an output for validation.
