stdio-common: Add scanf long double data for IEEE 754 binary64 format

Add Makefile infrastructure and 64-bit `long double' real input data for
targets switching between the IEEE 754 binary64 and IEEE 754 binary128
formats with `-mlong-double-64' and `-mlong-double-128'.  Use modified
output file names for the IEEE 754 binary64 format so as not to clash
with the names used for IEEE 754 binary128 format tests made with common
rules for the 'long double' data type.

Keep input data disabled and referring to BZ #12701 for entries that are
are currently incorrectly accepted as valid data, such as '0e', '0e+',
'0x', '0x8p', '0x0p-', etc.
