8357086: os::xxx functions returning memory size should return size_t

[GoeLin]

I backport this for parity with 21.0.11-oracle

Resolved two files, probably clean anyways:

src/hotspot/os/linux/os_linux.cpp
Resolve one chunk due to context. I omitted deleting an empty line that is not there in 25.

src/hotspot/share/runtime/os.hpp
Resolve one chunk due to context

Hi Götz,
the test changes in test/hotspot/jtreg/compiler/... look like a mistake.

[GoeLin]

HI @reinrich
thanks for pointing this out ... removed the edits to the test files.

[reinrich]
