Misc #19250: The require path of MJIT

Background

Since Ruby 3.2, MJIT is written in Ruby [Misc #18968]. We made it a require-able library instead of a builtin/prebuilt ISeq so that it will never be an extra overhead when MJIT is disabled. It's loaded with require "mjit/compiler" on prelude when --mjit is given.

However, while it's technically a "standard library", we don't mean to maintain its backward compatibility. To make it clear, it's implemented as RubyVM::MJIT::Compiler, implying that it's CRuby-specific by prefixing RubyVM::, and make every constant under RubyVM::MJIT a private constant. Even if users manually require it, the interface is private.

Discussion

For consistency with the constant name RubyVM::MJIT::Compiler and to make it even clearer that we don't guarantee backward compatibility, @ko1 (Koichi Sasada) suggested to change require "mjit/compiler" to require "ruby_vm/mjit/compiler".

I'm fine with both ways, so I'll do so after confirming that with @matz (Yukihiro Matsumoto).

No problem. Accepted.
