ZJIT: Allow ZJIT to use `#with_jit` hooks

[k0kubun]

In ruby#14044, we disabled the JIT hooks because ZJIT doesn't compile Array#each properly.

• Add a call into RubyVM::ZJIT.call_jit_hooks from zjit_enable https://github.com/ruby/ruby/pull/15219/files#r2535877447
• Drop && false from with_jit in jit_hook.rb
• Fix a bug in Array#each. We know that invokebuiltin for Array#each takes a reference to a local, which ZJIT doesn't support.
