  [MLIR][CMake] Add HEADER_LIBS and document CMake infrastructure

Add HEADER_LIBS as a flat list of literal library targets for generated headers
included without a link relationship. Resolve aliases and forward references,
accept imported libraries as already generated, follow nested HEADER_LIBS and
link interfaces, and reject missing, executable, utility, or generator-
expression entries with configure-time diagnostics. Represent header-only
edges in the common internal INTERFACE graph, including cyclic relationships.

Record links added by mlir_target_link_libraries for the same deferred ordering.
Add explicit, commented HEADER_LIBS edges for every audited header-only include
that is not covered by mlir-generic-headers, and keep this facility a rare
layering escape hatch.

Document dialects, interfaces, passes, PDLL, generated documentation, library
visibility, C API aggregation, tools, exports, standalone consumers, and the
generated-file model. Add a CMake fixture covering cycles, aliases, conditions,
LINK_ONLY, imported and ignored items, post-hoc links, and invalid providers.
Build each consumer independently from a clean state to verify transitive
generated-header ordering without unrelated generators masking missing edges.
