  [MLIR][SPIRVToLLVM] Implemented conversion for arithmetic ops and 3 bitwise ops.

Following the previous revision `D81100`, this commit implements a templated class
that would provide conversion patterns for “straightforward” SPIR-V ops into
LLVM dialect. Templating allows to abstract away from concrete implementation
for each specific op. Those are mainly binary operations. Currently supported
and tested ops are:
- Arithmetic ops: `IAdd`, `ISub`, `IMul`, `FAdd`, `FSub`, `FMul`, `FDiv`,  `FNegate`,
  `SDiv`, `SRem` and  `UDiv`
- Bitwise ops: `BitwiseAnd`, `BitwiseOr`, `BitwiseXor`

The implementation relies on `SPIRVToLLVMConversion` class that makes use of
`OpConversionPattern`.
