imx-cst: Add recipe

Add a recipe for the i.MX CST (Code Signing Tool) version 3.4.0.

The Code Signing Tool is used for secure boot implementation on
i.MX devices.

Example on how to use the CST tool to sign U-Boot on i.MX5/i.MX6/i.MX7:

https://source.denx.de/u-boot/u-boot/-/blob/master/doc/imx/habv4/guides/mx6_mx7_secure_boot.txt

Example on how to use the CST tool to sign U-Boot on i.MX8M:

https://source.denx.de/u-boot/u-boot/-/blob/master/doc/imx/habv4/guides/mx8m_spl_secure_boot.txt

Multiple layers include the imx-cst package and offer their version of
the recipes:

- meta-freescale
- meta-secure-imx
- meta-phytec

and probably more.

The idea of having imx-cst in meta-oe is to centralize and maintain
the efforts in a single location.

Move the existing imx-cst recipe from meta-freescale recipe to meta-oe.
