  [BOLT][AArch64] Check Last Element Instead of Returning `nullptr` in `lookupStubFromGroup` (#114015)

The current implementation of `lookupStubFromGroup` is incorrect. The
function is intended to find and return the closest stub using
`lower_bound`, which identifies the first element in a sorted range that
is not less than a specified value. However, if such an element is not
found within `Candidates` and the list is not empty, the function
returns `nullptr`. Instead, it should check whether the last element
satisfies the condition.
