gdb_server: support gdb target description
* Add a parameter in .get_gdb_reg_list() to return different
register lists as generating target description.
* Modify STRUCT REG to let gdb generate target description
according to register information.
The modified structure of register is
struct reg {
const char *name;
uint32_t number; /* for regnum="num" */
struct reg_feature *feature; /* for register group feature name */
bool caller_save; /* for save-restore="yes|no" */
void *value;
bool dirty;
bool valid;
bool exist;
uint32_t size;
struct reg_data_type *reg_data_type; /* for type="type" */
const char *group; /* for group="general|float|vector" */
void *arch_info;
const struct reg_arch_type *type;
};
