Add the TermuxSession class for linking a TerminalSession to an ExecutionCommand.

TermuxSession will maintain info for foreground Termux sessions. Each terminal session started by TermuxService will now be linked to a ExectionCommand that started it.

This also fixes bugs where newly created session in some cases were not being automatically selected and scrolled to, like when adding a named or failsafe session or those which were created for executable intents.
