gh-138580: Revert sys.float_info.iec_60559 boolean flag (#146501)

This reverts commit 68c7fad757f3a99fca257d11ce61adb78128a66c.

It looks like on practice the __STDC_IEC_559__ doesn't indicate
conformance to the standard. It can't be used to filter out tests
or to give some promises in documentation. See discussion in
the reverted PR thread:
