[PATCH] D115861: [LoongArch 4/n] Add basic tablegen infra for LoongArch

This patch introduces basic tablegen infra such as
LoongArch{InstrFormats,InstrInfo,RegisterInfo,CallingConv,}.td.

For now, only add instruction definitions for LoongArch basic integer
operations.
Our initial target is a working MC layer rather than codegen,
so appropriate SelectionDAG patterns will come later.

Depends on D115860 <https://reviews.llvm.org/D115860>
