pane: Ignore max tabs on terminal pane (#40740)

Closes #39901

I'm unsure as to which direction the team wants to go with this, but
this is the behavior of VSCode which is what this feature is based off
so i'm going with this.

Changes: 

1. Introduced a new argument to the `new` method on the Pane called
`ignore_max_tabs` that forces the `max_tabs` to None if it's true.
2. Added a new test `test_bypass_max_tabs_limit`.

Release Notes:

- Fixed: `max_tabs` Setting affecting the terminal pane.
