-----------
UefiCpuPkg/ExceptionHandler: Fix a context error in LoongArch64
On the LoongArch platform:
the a0 register can be used as both a function parameter and a return value.
Due to parameter EFI_SYSTEM_CONTEXT being overwritten by an invalid context
address,
when calling GetExceptionType, incorrect parameter address causes memory access
exception.

Log Message:
-----------
MdePkg/BaseLib: Fix an instruction write width error in LoongArch64
Cpucfg fetch is a 32-bit register, and AsmCpucfg's function
declaration is a 32-bit address storage operation in BaseLib.h,
So, fix it by replacing stptr.d with stptr.w instrcution.
