  Log Message:
  -----------
  [MLIR] Narrow generated-header prerequisites

Forward-declare IteratorType in TilingInterface.h instead of including all
structured-operation utilities. Include those utilities directly in SCF and
Tensor implementations that use their enum values and helpers, and remove
TilingInterface's dependency on the DialectUtils library.

Replace whole-library prerequisites with the specific Arith and GPU interface
generators. Drop VCIX's obsolete GPU prerequisite, and record the precise Ptr,
SPIR-V, Bufferization and Transform generators required by header consumers.

Pass Rewrite's conditional PDL links through add_mlir_library instead of
adding them afterward, so dependency and aggregation metadata see the same
links while preserving the PDL-disabled configuration.

Validate 289 TilingInterface clients without PCH, compile 13 affected source
files to objects, and compile Rewrite with PDL disabled. Configure both normal
and libMLIR-dylib builds and inspect the resulting dependency graph.
