tests: boards: rename espressif folder name

Current folder name is set to "espressif_esp32" and
might not reflect all kinds of SoCs as such as esp8684.
Rename the folder to "espressif" only.

 To run the test with twister, use the following command:
 
 .. code-block:: console
 
-   west twister -p <board> --device-testing --device-serial=/dev/ttyUSB0 -vv --flash-before -T tests/boards/espressif_esp32/rtc_clk

 If the external 32K crystal is connect to pins 32K_XP and 32K_XN, the test can be run with ``external_xtal`` fixture enabled:
