Fix clpf and dering signalling when used with ext-partition-types

Previously, when ext-partition-types and either clpf or dering were
enabled, the signalling for clpf/dering would not be encoded or decoded,
as the code to do so was inside a #if !CONFIG_EXT_PARTITION_TYPES block.
This caused many tests (eg, AV1/EndToEndTestLarge.EndToEndPSNRTest/0)
to fail with encode/decode mismatches.
