  [SCEV] Add initial matchers for SCEV expressions. (NFC) (#119390)

This patch adds initial matchers for unary and binary SCEV expressions 
and specializes it for SExt, ZExt and binary add expressions.

Also adds matchers for SCEVConstant and SCEVUnknown.

This patch only converts a few instances to use the new matchers to make
sure everything builds as expected for now.

The goal of the matchers is to hopefully make it slightly easier to
write code matching SCEV patterns.

Depends on https://github.com/llvm/llvm-project/pull/119389
