currently a collation lookup (collation name to collation id) is done (in get_collation_number_internal() ) by linearly scanning the array of collations.
This used to work fine, but the number of collations is constantly growing (MDEV-27009 MDEV-20912
It would be a good idea to change it to a hash lookup.
Same can be done for character sets, even though the number of charsets didn't grow that much.
