[vim/vim] Update last accessed tab page upon closing a tab (Issue #20965)

igorlfs created an issue (vim/vim#20965)

**Is your feature request about something that is currently impossible or hard to do? Please describe the problem.**
When using `<C-Tab>` to switch to the last accessed tab, closing the current tab turns the mapping into a NOOP, even if other tabs were accessed. It looks like the "last accessed tab" is just a single pointer, when it could be a "list".

More concretely:
1. `:tabnew`
2. `:tabnew`
3. `<C-Tab>`
4. `:tabclose`
5. `<C-Tab>` becomes NOOP, in spite of the first being accessed at some point

**Describe the solution you'd like**
Each tab should have a timestamp assigned to it (as in, its last access), and `<C-Tab>` should use this information to accurately switch to the last (accessed) tab, even after closing tabs. The implementation details don't matter too much, this is just the idea. 

**Describe alternatives you've considered**
This probably could be achieved with a remap and some autocmds, but it'd be nice to be a built-in feature.

**Additional context**
