Noah Misch d28cd3e7b2 At update of non-LP_NORMAL TID, fail instead of corrupting page header. 
The right mix of DDL and VACUUM could corrupt a catalog page header such
that PageIsVerified() durably fails, requiring a restore from backup.
This affects only catalogs that both have a syscache and have DDL code
that uses syscache tuples to construct updates.  One of the test
permutations shows a variant not yet fixed.

This makes !TransactionIdIsValid(TM_FailureData.xmax) possible with
TM_Deleted.  I think core and PGXN are indifferent to that.

Per bug #17821 from Alexander Lakhin.  Back-patch to v13 (all supported
versions).  The test case is v17+, since it uses INJECTION_POINT.
