[mlir][SPIRVToLLVM] Solve ExecutionModeOp redefinition and add OpTypeSampledImage into SPV_Type

1. To avoid two ExecutionModeOp using the same name, adding the value of execution mode in name when converting to LLVM dialect.
2. To avoid syntax error in spv.OpLoad, add OpTypeSampledImage into SPV_Type.
