Keeping around lastevent can delay garbage collection of a torn-down axes, and can also keep around an actual GUI event object (guiEvent) associated with a long-torn down widget, which can be problematic for some GUI toolkits.

Instead, only keep track of the last inaxes attribute.

Unfortunately there are no tests for axes_enter_event/axes_leave_event, but this can be manually tested by running the
event_handling/figure_axes_enter_leave.py example.

See #24820, #22211 (comment).
