net: prestera: manage matchall and flower priorities

matchall rules can be added only to chain 0 and their priorities have
limitations:
- new matchall ingress rule's priority must be higher (lower value)
than any existing flower rule;
- new matchall egress rule's priority must be lower (higher value)
than any existing flower rule.

The opposite works for flower rule adding:
- new flower ingress rule's priority must be lower (higher value)
than any existing matchall rule;
- new flower egress rule's priority must be higher (lower value)
than any existing matchall rule.

This is a hardware limitation and thus must be properly handled in
driver by reporting errors to the user when newly added rule has such a
priority that cannot be installed into the hardware.

To achieve this, the driver must maintain both min/max matchall
priorities for every flower block when user adds/deletes a matchall
rule, as well as both min/max flower priorities for chain 0 for every
adding/deletion of flower rules for chain 0.

net: prestera: acl: extract matchall logic into a separate file

This commit adds more clarity to handling of TC_CLSMATCHALL_REPLACE and
TC_CLSMATCHALL_DESTROY events by calling newly added *_mall_*() handlers
instead of directly calling SPAN API.

This also extracts matchall rules management out of SPAN API since SPAN
is a hardware module which is used to implement 'matchall egress mirred'
action only.
