vim-patch:9.0.1028: mouse shape test is flaky, especially on Mac OS (#23455)

Problem:    Mouse shape test is flaky, especially on Mac OS.
Solution:   Instead of starting all timers at the same time, start the next
            one in the callback of the previous one. (Yee Cheng Chin,
            closes vim/vim#11673)  Also use "bwipe!" instead of "close!" to avoid
            swap files remaining.
