Feature/spi nor flash wp hold pins

[JPHutchins]

The jedec,spi-nor compatible defines the use of wp-gpios (Write Protect) and hold-gpios (Hold) pins. Only one of the flash drivers, spi_flash_at45.c, initializes and uses wp-gpios and none of them initialize or use hold-gpios.

This PR adds initialization and implementation of wp-gpios to the more general spi_nor.c driver and initializes but does not implement hold-gpios (set to inactive).

Two build tests were added and they can be collected with west twister -c -p nrf52840dk_nrf52840 -T tests/drivers/flash.

spi_nor.c has been formatted with clang-format, so it may be helpful to look at the functional changes only in d551e5b.

Hello @JPHutchins, and thank you very much for your first pull request to the Zephyr project!

A project maintainer just triggered our CI pipeline to run it against your PR and ensure it's compliant and doesn't cause any issues. You might want to take this opportunity to review the project's Contributor Expectations and make any updates to your pull request if necessary. 😊

Hi @de-nordic , can you retrigger the "Run tests with twister / twister-build (8) (pull_request_target)" pipeline when you have chance, none of these changes should impact the failing test case. Thanks!

[de-nordic]

Please rebase the PR, there seems to be some problems, with CI, unrelated to the changes.

[JPHutchins]

@de-nordic @nashif LMK if you have any questions!

I am not certain how to address the pipeline failure. I am going to rebase again and see if it was already fixed.
