Add TSC2007 Touchscreen Controller

**Describe the problem you have/What new integration you would like**
Add the TSC2007 touchscreen controller. This is found in the new Adafruit TFT Featherwings, and also sold separately to interface with many touchscreens. It communicates via I2C.

**Please describe your use case for this integration and alternatives you've tried:**
This touchscreen controller is integrated into TFT featherwings, the display component of which is already integrated into ESPHome. The touchscreen component can't be currently utilized but is a very useful feature.

Start by reading the linked Adafruit_TSC2007 Arduino library and the TSC2007 datasheet to understand the I2C controller and touchscreen behavior. Then identify the ESPHome touchscreen integration entry point; done means the controller can be used with the supported TFT Featherwings and touchscreen input works.
