dt-bindings: iio: proximity: add ST VL53L1X ToF sensor

Add device tree binding documentation for the STMicroelectronics
VL53L1X Time-of-Flight ranging sensor connected via I2C.

vdd-supply is not made globally required to maintain backwards
compatibility with existing st,vl53l0x devicetrees that do not specify it.
