rb_feature_p: skip `get_expanded_load_path` for absolute paths Ref: https://github.com/fxn/zeitwerk/pull/308 ```ruby require 'benchmark' $LOAD_PATH << 'relative-path' autoload :FOO, '/tmp/foo.rb' puts Benchmark.realtime { 500_000.times do Object.autoload?(:FOO) end } ``` The above script takes 2.5 seconds on `master`, and only 50ms on this branch. When we're looking for a feature with an absolute path, we don't need to call the expensive `get_expanded_load_path`.
