imx-oei: move to dynamic-layers and add arm-toolchain

[hiagofranco]

The recipe depends on meta-arm-toolchain, therefore it should be on
dynamic-layers/arm-toolchain folder. Create it and make the
necessary changes for conf/layer.conf

Fixes: 61beaf5 ("recipes-bsp: introduce imx-oei recipe")

I believe we can make this recipe conditional to the toolchain layer instead of the full arm layer. Could you give it a try?

https://git.yoctoproject.org/meta-arm/tree/meta-arm/conf/layer.conf

Either way, I marked the recipe to do the backport automatically, so once we merge this pull request, it's going to create automatically the backport pull request for us.

@thochstein, could you ask internally why we need to use the arm toolchain instead of the general one? I'd prefer to drop that dependency and make the recipe general.

That would be done in a future release, but it would be nice to consider this improvement.

I am not sure if I got it correct, but I pushed the changes. Please have a look.

We need the generic compiler because the output runs on an m-core, not the main core.
