[ruby/irb] Unroll extension method generation

(https://github.com/ruby/irb/pull/882)

* Unroll extension method generation

Given we only have 2 remaining extension setter methods, both of which
only take 1 argument and don't have any alias, the current method generation
logic is overly complicated.

This commit simplifies the method generation logic by simply defining
the methods directly in the `IRB::Context` class.

* Fix use_loader extension
