Add Atmel CryptoAuthLib to extras

Browse source 
This is Atmel/Microchip's official library for interfacing
to the Atmel ATECC508 chip.  The submodule points to their
repository in GitHub.

Additionally, this includes the HAL necessary to use this library
in esp_open_rtos using the i2c library in extras/i2c.  I have also
included a tool I wrote to play with the chip as an example under
examples/atcatool.

The extras module currently overrides atca_iface.h to fix bug in
cryptoauthlib (c11-only feature, which breaks c++ builds that want
to use cryptoauthlib)
