The 1st command below correctly reports trailing spaces, for Unix and Windows

The 2nd one incorrectly reports all lines.
grep -sHn -i " [[:cntrl:]]*$" *.vhd
grep -sHn -i "\s[[:cntrl:]]*$" *.vhd
I don't see a bug. The latter command is equivalent to:
grep -Hins '[[:space:]][[:cntrl:]]*$' *.vhd
and if the input files use Microsoft CRLF format then [[:space:]] matches the CR
at the end of every line and [[:cntrl:]]* matches the empty string after the CR.
Possibly you need to use Unix LF format, or use the --text option, or something
like that.
Marking the bug as done.
IIRC even Cygwin dropped Windows text handling in coreutils, findutils, grep,
sed, etc. about 2018 to be consistent with other POSIX platforms.
Use d2u/dos2unix or u2d/unix2dos in pipes to convert, or equivalent, such as
tr -d '\r', sed -e 's/\r//g', awk -e '{gsub(/\r/,"")'.
Cygwin users may be able to compensate by remounting the filesystem with a
"text" mount option -o text or the equivalent in an /etc/fstab entry, but I am
unsure if anyone has tested using that option nowadays.
