Frontmost Window Title sensor

[skrenes]

Is your feature request related to a problem? Please describe.
The "Frontmost App" sensor is great for automations but taking it a step further with an additional sensor called "Frontmost Window Title" would be greatly beneficial for automations and even time tracking.

Describe the solution you'd like
A new sensor would be better than adding an attribute to the "Frontmost App" sensor, mostly because some people may not like how invasive this proposed sensor is and want the ability to turn it off.

This would be awesome. I currently have a server turn on via Wake-On-Lan from Home Assistant when I open VSCode. This is in anticipation of me planning to connect to the server to work on some code. However, sometimes I only want to work on a personal project and would like the server to stay off. If I could detect certain words in the window title, I could choose better times to turn on the server.
