[ASan][libc++][NFC] refactor vector annotations arguments (#78322)

This commit simplifies ASan helper functions in `std::vector` by
removing arguments which can be calculated later.

Short term it improves readability of helper functions in `std::vector`.

Long term it aims to help with a bigger refactor of container
annotations.
