feat: added JWT handling for limit disclosure Presentation Definition query

[mishasizov-SK]

Title:
Added JWT handling for limit disclosure Presentation Definition query.

Summary:
After new credential is created based on limit disclosure constraints:

credential, err = createNewCredential(constraints, credentialSrc, template, credential, opts...)
if err != nil {
     return nil, fmt.Errorf("create new credential: %w", err)
}

it always returned in JSON-LD format.

Then, down the code, we check is it JWT in merge func

vcFormat := FormatLDPVC
if credential.JWT != "" {
     vcFormat = FormatJWTVC
}
.....
  desc := &InputDescriptorMapping{
	PathNested: &InputDescriptorMapping{
		Format: vcFormat,
	},
}

I added a code that calculates JWT field in limited disclosure VC based on existing claims.
