RFR: 8357826: Avoid running some jtreg tests when asan is configured [v6]

[Matthias Baesken]

> There are a couple of jtreg tests, especially in the HS area, with very special assumptions about memory layout/sizes .
> Those fail when the address sanitizer is configured ( --enable-asan ).
> The change adds a way to tag those tests with 'requires' so that they can be avoided easily when running jtreg tests with ASAN enabled.
> Adjusting the tests for "pleasing" the sanitizer is not always desired (if possible for some tests it can be done later) .
> While at it, also same is also added for ubsan .
