[jdk15u-dev] RFR: 8240487: Cleanup whitespace in .cc, .hh, .m, and .mm files

[Vladimir Kempik]

Please review this patch for 15u-dev.
applied almost cleanly, I have to remove last chunk in src/jdk.hotspot.agent/macosx/native/libsaproc/MacosxDebuggerLocal.m
from original [patch](https://github.com/VladimirKempik/jdk/commit/c32923e06fc94c2a2ad8b9dd803aad1ed5386505) as it was already present in jdk15u-dev and wasn't needed.
Very safe, fomatting only change, needed for rest of JNF removal patches to apply more cleanly
