fix: use data source for size custom formats to work around provider set key bug

The devopsarr sonarr provider cannot handle float min/max values in
SizeSpecification as set element keys. Remove size custom formats from
terraform management and look up their IDs via a data source instead.
Also change variable types from map(any) to any to allow heterogeneous
quality profile structures.
