  [libc++] Fix vector::append_range growing before the capacity is reached (#183264)

Currently `vector::append_range` grows even when appending a number of
elements that is exactly equal to its spare capacity, which is
guaranteed by the standard to _not_ happen.

Fixes #183256

(cherry picked from commit d6fcf47a893475f6f3dbcace29093297b7e9f366)
