The PR adds the support of CoreDump debugging for RISC-V 64. It implements new `RegisterContextCorePOSIX_riscv64` class. Also, the contribution fixes `GetRegisterCount()` -> `GetRegisterSetCount()` misprint in `RegisterContextPOSIX_riscv64::GetRegisterSetCount()` method, which leaded to `set && "Register set should be valid."` assertion during `register info aX` command call. The patch was tested (on coredumps generated for simple Integer/FP calculation code) for _cross x86_64 -> RISCV_ and _native RISCV_ LLDB builds. There were performed basic LLDB functionality tests, such as: - CoreDump file load - Backtrace / frames - GP/FP registers read/info/list - Basic switch between threads - Disassembler code - Memory regions read / display
