RFR: 8340801: Disable ubsan checks in some awt/2d coding [v2]

Tue Oct 1 13:45:56 UTC 2024

> There is some old awt/2d coding where warnings occur when running with ubsan enabled binaries.
> However at most of these locations the coding should work (at least on our supported platform set) so the warnings can be disabled at least for now.
> 
> The change adds a macro ATTRIBUTE_NO_UBSAN  similar to what we already use in Hotspot coding.
