[lldb][RISCV] Use uint64_t for emulating ADDI (#160550)
In RISC-V, the same instruction is used for both signed and unsigned
additions.
Signed integer overflow is undefined behavior in C++, but signed integer
overflow is defined behavior when using ADDI in RISC-V.
As we are emulating the RISC-V behavior we should be using uint.
This fix the failure with ubsan introduced by #159842:
lldb/source/Plugins/Instruction/RISCV/EmulateInstructionRISCV.cpp:807:40:
runtime error: signed integer overflow: -9223372036854775808 + -16
cannot be represented in type 'int64_t' (aka 'long')
