io: Refactor close_range and closefrom
Now that Hurd implementis both close_range and closefrom (f2c996597d), we can make close_range() a base ABI, and make the default closefrom() implementation on top of close_range(). The generic closefrom() implementation based on __getdtablesize() is moved to generic close_range(). On Linux it will be overriden by the auto-generation syscall while on Hurd it will be a system specific implementation. The closefrom() now calls close_range() and __closefrom_fallback(). Since on Hurd close_range() does not fail, __closefrom_fallback() is an empty static inline function set by__ASSUME_CLOSE_RANGE. The __ASSUME_CLOSE_RANGE also allows optimize Linux __closefrom_fallback() implementation when --enable-kernel=5.9 or higher is used. Finally the Linux specific tst-close_range.c is moved to io and enabled as default. The Linuxism and CLOSE_RANGE_UNSHARE are guarded so it can be built for Hurd (I have not actually test it). Checked on x86_64-linux-gnu, i686-linux-gnu, and with a i686-gnu build.
