Drop MatchByTypeName check in opIsPartOfiPTRPattern

Matching by type name can make incorrect assumption of memory operands,
when the destnation register and base register share the same type of
GPR. Drop this logic for now. This commit fixes the destination register
info of load instructions of LoongArch ISA.

Fixes capstone-engine/capstone#2700.
