Hide unavailable backends & Add tooltip over backend count

Hides unavailable backends from the user and if the program is launched without any backends made, it shows an error message to them stating no backends were found and to make them using the 'make' command

Add tooltip when hovering over backend count label

hovering over the new label that shows the backend count will explain what the numbers are, and show the users which backends are not available or built
