Allow relative path for SOL004 descriptors import
Allow the use of relative path on SOL004 descriptors imports. Resolves imports with "/", "../" or "./" entries during validation and package processing. Validate if the reference is inside the package. Fix problem where imported descriptor files, described as a non string scalar yaml entry, were not being checked by the validator. Change-Id: Ie5a32736b6090b4adf178e8714f7460bcd068def Issue-ID: SDC-2422 Signed-off-by: andre.schmid <andre.schmid@est.tech>
