Subject: [ruby/fiddle] Use have_header and have_type to detect memory view
 availability

Fix https://github.com/ruby/fiddle/pull/84

It may detect ruby/memory_view.h for system Ruby that is installed in
/usr.

We can use RUBY_API_VERSION_MAJOR to detect memory view availability
because memory view is available since Ruby 3.0.

Reported by Jun Aruga. Thanks!!!
