[RISCV] enable LTO support, pass some options to linker.
Summary:
1. enable LTO need to pass target feature and abi to LTO code generation
RISCV backend need the target feature to decide which extension used in
code generation.
2. move getTargetFeatures to CommonArgs.h and add ForLTOPlugin flag
3. add general tools::getTargetABI in CommonArgs.h because different target uses different
way to get the target ABI.
