This commit adds the asynchronous UART API testing support on the SAM
R21 Xplained Pro board.

The SERCOM3 module is used as the secondary loop-back UART, which is
required to run this test.

Note that no external UART loop-back connection is necessary to run
this test, because the SERCOM3 UART TX and RX pads are configured to be
internally connected; it is, however, still necessary to configure the
pinmux because the module pads are not connected until the pinmux is
configured.

To be rebased on top of #24572 (blocked by #24572). Done

@nandojve Can you test if this works on your SAM R21 Xplained Pro board?

Modified the test to use SERCOM3 on PA22/23 instead of SERCOM2 on PA12/13, since those pins are free and connected to an external connector on the board.
