Firstly I follow [this blog](https://cristianadam.eu/20190501/bundling-together-static-libraries-with-cmake/) to recursively collect MLIR/LLVM related dependencies for our own library (libMy.a) or binary (MyBinary). (And print the dependencies tree for better visualization)

E.g:
```
....
|  |  |  |  |  |  |--MLIRArithDialect(depth:6, dep_count:8)
|  |  |  |  |  |  |  |--MLIRCastInterfaces(depth:7, dep_count:2)
|  |  |  |  |  |  |  |--MLIRDialect(depth:7, dep_count:2)
|  |  |  |  |  |  |  |--MLIRInferIntRangeCommon(depth:7, dep_count:3)
|  |  |  |  |  |  |  |  |--MLIRInferIntRangeInterface(depth:8, dep_count:2)
|  |  |  |  |  |  |  |--MLIRInferTypeOpInterface(depth:7, dep_count:2)
|  |  |  |  |  |  |  |--MLIRUBDialect(depth:7, dep_count:2)
|  |  |  |  |  |--MLIRLLVMDialect(depth:5, dep_count:15)
|  |  |  |  |  |  |--MLIRCallInterfaces(depth:6, dep_count:2)
|  |  |  |  |  |  |--MLIRControlFlowInterfaces(depth:6, dep_count:2)
|  |  |  |  |  |  |--MLIRDataLayoutInterfaces(depth:6, dep_count:2)
|  |  |  |  |  |  |--MLIRFunctionInterfaces(depth:6, dep_count:2)
|  |  |  |  |  |  |--MLIRMemorySlotInterfaces(depth:6, dep_count:2)
|  |  |  |  |  |  |--MLIRSideEffectInterfaces(depth:6, dep_count:2)
|  |  |  |  |  |  |--LLVMAsmParser(depth:6, dep_count:3)
|  |  |  |  |  |  |  |--LLVMBinaryFormat(depth:7, dep_count:2)
|  |  |  |  |  |  |  |  |--LLVMTargetParser(depth:8, dep_count:1)
|  |  |  |  |  |  |  |--LLVMCore(depth:7, dep_count:8)
|  |  |  |  |  |  |  |  |--LLVMRemarks(depth:8, dep_count:2)
...
```

Meanwhile, I also try dump the linker map of binary (MyBinary) by adding following code to CMakeLists.txt.
```
set(MyBinary_LINKER_MAP_FILE ${CMAKE_CURRENT_BINARY_DIR}/MyBinary.map)
target_link_options(MyBinary PRIVATE LINKER:-Map=${MyBinary_LINKER_MAP_FILE})
```

Then use regex to extract all libMLIR/LLVM*.a from MyBinary.map. By comparing these with the dependencies obtained from CMake functions and linker maps, I notice that the "linker map" method has fewer dependencies and eliminates unnecessary libraries.

Then I start manually remove this unneeded libraries in CMakeLists.txt and open this PR.
