RFR: 8325456: Rename nsk_mutex.h

Thu Feb 8 05:17:06 UTC 2024

Please review this trivial change that renames the file
test/hotspot/jtreg/vmTestbase/nsk/share/native/nsk_mutex.h to nsk_mutex.hpp.

Testing: mach5 tier1

The usage is odd.  The header is only included by the associated .cpp file.
That .cpp file is included by only one other file, and that file is compiled.
