Consider .class a source extension during search#9006

The logic here was ported from CRuby, which only considers .rb to be a source extension. This causes our logic to think a filename like "foo.class" is not a source file and try to load it as either "foo.class.rb" or "foo.class.class". This is the cause of jruby#8758 and prevents explicitly loading precompiled Ruby sources using the filename with .class extension. The fix here modifies the source extension check to also consider other configured source extensions, so that when .class searching is enabled, we will properly treat `require "foo.class"` as a source file. Fixes jruby#8758
This enables precompiled .class files to be loaded with require, since that behavior was made optional in JRuby 9.3, and adds a test that confirms it works for a full filename, reported as broken in jruby#8758.

This affects all releases since 9.3.0.0 and could be backported all the way if we choose.
