[ruby/rdoc] Treat multiple Ruby methods calling the same C method as aliases

Previously, only calls to rb_define_alias were treated as aliases.
This treats calls to rb_define_method with the same C function as
aliases, with the first function defined being the primary method.

This move the dedup code from the C parser to AnyMethod, and has
AnyMethod look in its aliases to find the call_seq.

Switch the deduplication code to remove lines matching one of the
other aliases, instead of only keeping lines matching the current
alias.  The previous approach could eliminate all call_seq lines
in cases where no line matched.  This was necessary to pass
tests when call_seq does deduplication by default.

The only change to the darkfish template is to not perform
unnecessary work by deduplicating twice.
