Cygwin: fhandler/proc.cc(format_proc_cpuinfo): Linux 6.10 flags resync

Browse Source 
Linux 6.10 changed the content of cpufeatures.h to require explicit
quoted flag names for output in comments, instead of requiring a null
quoted string "" at the start of comments to suppress flag name output.
As a result, some flags (not all for output) were renamed and others moved:

- change dts to ds; move intel_ppin down; swap ibpd and ibrs;
- change some flag names and descriptions that are not output.
