Remove deprecated InnoDB file format parameters

The following options will be removed:

innodb_file_format
innodb_file_format_check
innodb_file_format_max
innodb_large_prefix

They have been deprecated in MySQL 5.7.7 (and MariaDB 10.2.2) in WL#7703.

The file_format column in two INFORMATION_SCHEMA tables will be removed:

innodb_sys_tablespaces
innodb_sys_tables

Code to update the file format tag at the end of page 0:5
(TRX_SYS_PAGE in the InnoDB system tablespace) will be removed.
When initializing a new database, the bytes will remain 0.

All references to the Barracuda file format will be removed.
Some references to the Antelope file format (meaning
ROW_FORMAT=REDUNDANT or ROW_FORMAT=COMPACT) will remain.

This basically ports WL#7704 from MySQL 8.0.0 to MariaDB 10.3.1:
