RFR: 8321550: Update several runtime/cds tests to use vm flags or mark as flagless

[Calvin Cheung]

Simple update to a few CDS tests:

- add `@requires vm.flagless` if the test is using `ProcessTools.createLimitedTestJavaProcessBuilder()`;
- some tests are using `ProcessTools.createLimitedTestJavaProcessBuilder()` by mistake; change it back to `ProcessTools.createTestJavaProcessBuilder()`.

Passed tiers 1 - 3 testing.
