testsuite: Add filters for default_packed targets [PR116155]

A few recent C++ test cases are assuming non-zero structure field
padding.  Consequently they fail for targets defaulting to packed
structure layout.  Fix by adding the necessary DejaGnu filters.

There are no test result changes for x86_64-pc-linux-gnu:
  $ dg-cmp-results.sh -v -v "" pre-g++.sum post-g++.sum
  -> No differences.

The tests for pru-unknown-elf changed from FAIL to UNSUPPORTED.

	PR testsuite/116155

gcc/testsuite/ChangeLog:

	* g++.dg/abi/nsdmi-aggr1a.C: Disable test for effective
	default_packed targets.
	* g++.dg/abi/nullptr-align2.C: Ignore warning for default_packed
	targets.
	* g++.dg/cpp1z/aligned-new9.C: Disable test for effective
	default_packed targets.
	* g++.dg/cpp2a/bit-cast5.C: Ignore dg-error for default_packed
	targets.
	* g++.dg/pr53037-1.C: Match any default packing value.
	* g++.dg/warn/Wpadded-1.C: Ignore warning for default_packed
	targets.
