MDEV-12218 Clean up InnoDB parameter validation
Bind more InnoDB parameters directly to MYSQL_SYSVAR and remove "shadow variables". innodb_change_buffering: Declare as ENUM, not STRING. innodb_flush_method: Declare as ENUM, not STRING. innodb_log_buffer_size: Bind directly to srv_log_buffer_size, without rounding it to a multiple of innodb_page_size. LOG_BUFFER_SIZE: Remove. SysTablespace::normalize_size(): Renamed from normalize(). innodb_init_params(): A new function to initialize and validate InnoDB startup parameters. innodb_init(): Renamed from innobase_init(). Invoke innodb_init_params() before actually trying to start up InnoDB. srv_start(bool): Renamed from innobase_start_or_create_for_mysql(). Added the input parameter create_new_db. SRV_ALL_O_DIRECT_FSYNC: Define only for _WIN32. xb_normalize_init_values(): Merge to innodb_init_param().
