refactor(efloat): nexttoward builds target directly from long double (#1162)

Now that efloat's long double conversion is correct (#1160), nexttoward no longer
needs to route its direction argument through double. It constructs the target
straight from long double, so no direction information is lost. On platforms
where LONG_DOUBLE_SUPPORT is off (long double aliases double), the efloat(double)
constructor is selected instead -- also exact.

Added a regression guard: a target within one double-ULP of x but distinguishable
in long double (1 + 2^-60) now supplies a valid direction and steps; the old
double-cast collapsed it to == x (no step). Gated on
sizeof(long double) > sizeof(double). PASS on gcc and clang.

Relates to #1120, #1160
