A previous change was added to allow the `getpriv` command to dump ec256
keys in both openssl and pkcs8. That PR did not touch other key file
types which resulted in errors using that command with RSA, X25519, etc.
This commit generalizes the passing of the `format` parameter, so each
key type can decide which format it allows a dump to be produced in,
and what default to use.

Update `getpub` with new `lang` option, "pem", which allows exporting a
public key as a PEM file. This can later be distributed to be used for
encrypting an image, and gets away with having to use openssl for this
step.

Add SPDX headers indicating the Apache-2.0 license to the scripts in the
