[thread-cert] relax TLV type checks in pktverify (#10627)

Browse Source 
This commit modifies thread-cert scripts utilizing `pktverify` to
adopt a more flexible approach to TLV type checking. Specifically, it
replaces strict equality (`==`) or strict subset (`<`) checks with a
subset or equal check (`<=`) when verifying the presence of TLVs in a
message. This adjustment ensures that test scripts adhere to the
principle of ignoring extra or unknown TLVs, thereby future-proofing
them against potential protocol updates that might introduce new
TLVs.
