Fix PR target/99184: Wrong cast from double to 16-bit and 32-bit ints
this patch fixed PR target/99184 which incorrectly rounded during 64-bit
(long) double to 16-bit and 32-bit integers.
The patch just removes the respective roundings from
libf7-asm.sx::to_integer and ::to_unsigned. Luckily, LibF7 does nowhere
use respective functions internally, the only user is in libf7.c::f7_exp
which reads
f7_round (qq, qq);
int16_t q = f7_get_s16 (qq);
so that f7_get_s16() operates on an already rounded value, and therefore
this code works unaltered with or without rounding in to_integer.

* libf7-asm.sx (to_integer, to_unsigned): Don't round 16-bit
and 32-bit integers.
