LOG: [mlir][cmake] Export MLIR_LINK_MLIR_DYLIB in MLIRConfig.cmake (#207336)

Fixes #197175.

`MLIRConfig.cmake` did not propagate `MLIR_LINK_MLIR_DYLIB` to out-of-tree MLIR users. Standalone projects using `find_package(MLIR CONFIG)` and `include(AddMLIR)` therefore could not observe the value used by `mlir_target_link_libraries(...)` when MLIR was configured with `-DMLIR_LINK_MLIR_DYLIB=ON`.

Export `MLIR_LINK_MLIR_DYLIB` through `MLIRConfig.cmake`.

AI tool usage:
I used ChatGPT/Codex to help understand the issue, identify the analogous LLVM CMake pattern, and draft the PR description. I manually reviewed the final patch and verification.
