6fb51f5a - [MLIR] Default PDL off for dependency-only builds (#233108)

[MLIR] Default PDL off for dependency-only builds (#233108) Default PDL support in PatternMatch to off whenever MLIR is configured only as a dependency. Keep the existing default for explicitly enabled MLIR builds and preserve user-provided PDL settings. This speeds up clang build with CIR enabled. Assisted-by: Codex
