[libc++] Simplify vector<bool> fill constructors (#160521)

#119632 introduced a code size and performance regression. This was
verified by running the included benchmark against trunk and trunk with
#119632 reverted. Instead of actually reverting that patch, we can
inline `__construct_at_end` into the few places it's used instead,
simplifying the implementation further (by not handling special cases we
never actually encounter).
