  mapogcfilter: limit filter operation count

Reject filters with more than 256 operations before converting logical operands into a right-deep binary tree. This keeps recursive validation, expression generation, and cleanup within a bounded stack depth.

Add a WMS GetMap regression test that verifies an oversized Or filter returns InvalidParameterValue without crashing.
