Remove the MonadFail P instance
There were two issues with this instance:
* its existence meant that a pattern match failure in the P monad would
produce a user-visible parse error, but the error message would not be
helpful to the user
* due to the MFP migration strategy, we had to use CPP in Lexer.x,
and that created issues for #17750
Updates haddock submodule.
