ZJIT: Remove JITState#iseq (#16774)

While working on implementing a new inliner for ZJIT, I keep running into an issue where the wrong iseq pointer is being used. Since JITState#iseq and FrameState#iseq end up being the same value in the absence of inlining, I don't think we've been all that rigorous about using the "correct" one in a given context. I've been migrating to FrameState#iseq in my inliner work and adapting on each rebase. But, having looked at this code for a little while, I think we can remove JITState#iseq....

ZJIT: Add a YarvInsnIdx type for clarity (#16783)

Remove discard qualifiers warning with C23 strchr

C23 has qualifier-preserving standard library functions, so calling
strchr with a const char * will return a const char *. We can change

Make rb_enc_str_coderange inlinable by default

This is a generalization of the optimization done in re.c

Code that deal with coderange can benefit significantly from
avoiding that function call, assuming coderange is often already...

Extends the @_init guard to def_method so that an ERB object created

class.c: Make cvc_tbl a managed object

[Bug #21952]

Solves the double-free or use after-free concern with boxes.
Now entries can safely be used for copy-on-write.

Also is likely necessary to make it save to read cvar from
secondary ractors, as allowed since: ab32c0e690b805cdaaf264ad4c3421696c588204
