[meta-zephyr][PATCH 1/2] bossa-native: Add Arduino variant of the bossa flashing tool

[Andrei Gherzan]

From: Stefan Schmidt <stefan.schmidt@huawei.com>

This native recipe will be used to streamline the flashing of out
Arduino Nano 33 BLE target. Until now we have pointed to the full
Arduino IDE to get it installed and setting the PATH correctly before
any flashing would work. Having the tool supplied under the hood for
flashing will simplify documentation and support.

[meta-zephyr][PATCH 2/2] zephyr-flash-bossac.bbclass: Use internal bossac tool instead looking up PATH

[Andrei Gherzan]

From: Stefan Schmidt <stefan.schmidt@huawei.com>

Instead of looking in PATH on the host to find bossac we now depend on the
native variant we build and set the path to our yocto build tool.
