gdb_server, rtos: Fine-grained RTOS register access
1. Add get_thread_reg() to rtos. It's used in rtos_get_gdb_reg() to read the value of a single register, instead of reading all register values by calling get_thread_reg_list(). 2. Add set_reg() to rtos. gdb_server uses this to change a single register value for a specific thread. 3. Add target_get_gdb_reg_list_noread() so it's possible for gdb to get a list of registers without attempting to read their contents. The clang static checker doesn't find any new problems with this change.
