JDK-8275440: Remove VirtualSpaceList::is_full()

[tstuefe]

This function is only used from a single gtest. Ioi remarked that it is not threadsafe. The context in which it is used is not multithreaded, but nevertheless I opted to remove the function and modified the test to make the condition somewhat more generic.

This trades a slight decrease in complexity with a very minor decrease in test precision, but that is fine.

Test:

• manual gtests
• GHAs
• ran the metaspace jtreg gtests, which execute gtests with various metaspace modes
