wifi: rtw88: 8822c: extend supported probe request size

Some WSC IEs require size larger than we current supports. Extend size
to fit those demands. Separate the registered scan IE length by IC so
settings can be independent.

Since old firmware uses fewer page number, define a firmware feature to
be compatible with various firmware version.
