Remove various useless #include (#22581)

This removes leftover win32/param.h / <sys/param.h> includes from files that
do not use any of the macros provided by those headers (MAXPATHLEN,
MAXHOSTNAMELEN, howmany, roundup).

It also removes local Windows O_RDONLY -> _O_RDONLY aliases from files where
O_RDONLY is not used.
