  [libc++] Fix throwing away smaller allocations in string::shrink_to_fit (#115659)

Currently `string::shrink_to_fit()` throws away any allocations which
return more capacity than we requested, even if that allocation is still
smaller than the current capacity. This patch fixes this to compare the
returned allocation against the current capacity of the string instead
of against the requested capacity.
