We were using the wrong close icon for the settings tab. This is a side effect of `TerminalTab` overriding `TabBase`'s implementation.

## Detailed Description of the Pull Request / Additional comments
Currently the tab tool tip is the tab's title.
The PR teaches the TabBase to check if there is a switch to tab command
associated with the current tab index,
if so concatenates the the relevant mapping to the too tip.
Of course, prefers user defined bindings to the default ones.
Moved tool tip logic to TabBase so SettingsTab has tooltip as well.
First step towards #8415:
* Introduce `PaletteItem` and derive from it to provide native support
for tabs and command lines (`ActionPaletteItem` / `TabPaletteItem`,
`CommandLinePaltteItem`)
* Remove business logic behind PaletteItem from palette (aka dispatch
commands and preview tabs externally)
In preparation for the Settings UI, we needed to make some changes to
Tab to abstract out shared, common functionality between different types
of tab. This is the result of that work. All code references to the
settings have been removed or reverted.
Contains changes from #8053, #7802.
The messages below only make sense in the context of the Settings UI,
which this pull request does not bring in. They do, however, provide
valuable information.
From #7802 (@leonMSFT):
> This PR's goal was to add an option to the `OpenSettings` keybinding to
> open the Settings UI in a tab. In order to implement that, a couple of
> changes had to be made to `Tab`, specifically:
>
> - Introduce a tab interface named `ITab`
> - Create/Rename two new Tab classes that implement `ITab` called
> `SettingsTab` and `TerminalTab`
>
From #8053:
> `TerminalTab` and `SettingsTab` share some implementation details. The
> close submenu introduced in #7728 is a good example of functionality
> that is consistent across all tabs. This PR transforms `ITab` from an
> interface, into an [unsealed runtime class] to de-duplicate some
> functionality. Most of the logic from `SettingsTab` was moved there
> because I expect the default behavior of a tab to resemble the
> `SettingsTab` over a `TerminalTab`.
>
> ## References
> Verified that Close submenu work was transferred over (#7728, #7961, #8010).
>
> ## Validation Steps Performed
> Check close submenu on first/last tab when multiple tabs are open.
>
> Closes#7969
