configs: Add google-pixel fragment config for Pixel 3, 3 XL, 5

Introduce a fragment config for the Pixel 3, Pixel 3 XL, Pixel 5.

On these devices, U-Boot is chainloaded via fastboot. However, due to
additional requirements added by Google, the image header must have
a specific value for the text offset.
This is solved by setting CONFIG_TEXT_BASE to 0x80080000 in U-Boot.
