  [libc][NFC] Unify `FPBits` implementations (#76033)

`FPBits` is currently implemented as a general case and a specialization
for `long double` when `long double` is x86 80-bit extended precision.
This patch is a first of a series to provide an implementation based on
`FPType` instead of the C++ float type (which implementation is
architecture dependent).
