[MLIR] Fix typo of the word "pattern" in CAPI and docs (llvm#163780)

This includes the rename from `mlirOpRewritePattenCreate` to `mlirOpRewritePatternCreate` in CAPI, and other typo fixes in docs and code comments.

 *   It is always good to eliminate operations entirely when possible, e.g. by

+*   Patterns with expensive running time (i.e. have O(n) complexity) or
     complicated cost models don't belong to canonicalization: since the
     algorithm is executed iteratively until fixed-point we want patterns that
