Subject: [PATCH] Use noinline version of accessing current ec

On universal.arm64e-darwin22 with clang 15.0.0 (I didn't check
details yet) accessing `ruby_current_ec` directly causes
assertion violation `VM_ASSERT(ec == rb_current_ec_noinline())`
on `rb_current_execution_context()`, maybe because TLS accessing
issue.
