MDEV-14180 Automatically disable key rotation checks for file_key_managment pluginbb-10.6-MDEV-14180_1

- InnoDB iterates the fil_system space list to encrypt the
tablespace in case of key rotation.But it is not necessary
for any encryption plugin which doesn't do any key rotation.
InnoDB should avoid key rotation for file key management
encryption plugin.

Introduce new encryption service called encryption_set_no_rotation()
and encryption_get_rotation(). Encryption plugin should
call encryption_set_no_rotation() in case it doesn't
support key rotation. Introduce a new variable called
srv_encrypt_rotate and it should be assigned via
encryption_get_rotation(). If it doesn't do key rotation
then InnoDB should add the tablespace to rotation list.
