Remove ARMFPA support and Q_DOUBLE_FORMAT detection

Remove the -armfpa option the config.tests/unix/doubleformat*
detection. The places where we used QT_ARMFPA and Q_DOUBLE_FORMAT
has been removed as well.

Rationale: ARM FPA with GCC does not work with EABI. Qt currently
does not support compiling without EABI, making ARM FPA an
impossibility. It is unknown whether other compilers provide ARM FPA
support with EABI. Support for ARM FPA can be re-added in the future
should the need arise, but since ARM VFP is available for ARMv5 and up,
we should encourage implementors to instead use soft-floats or VFP.
