Implement Or Patterns (#22596)

This commit introduces a new language extension, `-XOrPatterns`, as described in
GHC Proposal 522.

An or-pattern `pat1; ...; patk` succeeds iff one of the patterns `pat1`, ...,
`patk` succeed, in this order.

See also the summary `Note [Implmentation of OrPatterns]`.
