RFR: 8338929: Make Metaspace::deallocate space-aware [v3]

[Thomas Stuefe]

> For ucoming Lilliput changes, as well as to simplify [JDK-8338526](https://bugs.openjdk.org/browse/JDK-8338526), we should make Metaspace::deallocate space-aware (as in, instead of having to tell it where the pointed-to block resides, it should know it on its own). 
> 
> As of now, callers need to tell the function of the deallocated block is in class space or in non-class metaspace. That is unnecessary and won't work for TinyCP. The deallocation function can do this better on itself by doing a range check on the class space range.
