[DISTRO] Add security packagegroup

This adds the generic support for TPM into the Clea OS Embedded distro.
Only the tpm-related packages will be installed. For specific needs, the customer will need to add additional packages on their side:
e.g. for OpenSSL:

CORE_IMAGE_EXTRA_INSTALL += " \
    tpm2-openssl \
    libtss2-tcti-device \
"

Or should we include them into the packagegroup as well?

On the Machine side, tpm or tpm2 needs to be added to MACHINE_FATURES: meta-seco-mtk!123 (486646a7)

Tested with OpenSSL on E58:

root@seco-genio700-e58:~# openssl list -providers -provider tpm2 -verbose
Providers:
  tpm2
    name: TPM 2.0 Provider
    version: 1.1.0
    status: active
    build info: 1.1.0
    gettable provider parameters:
      name: pointer to a UTF8 encoded string (arbitrary size)
      version: pointer to a UTF8 encoded string (arbitrary size)
      buildinfo: pointer to a UTF8 encoded string (arbitrary size)
      status: integer (arbitrary size)
root@seco-genio700-e58:~# openssl genpkey -provider tpm2 -algorithm RSA -out testkey.priv && cat testkey.priv
