The wallet should respect the DCQL multiple parameter

[psteniusubi]

If a presentation request matches claims across multiple credentials, the wallet lets me present multiple credentials even if the DCQL multiple parameter is not true.

See OpenID4VP DCQL multiple parameter

Steps to reproduce

1. Go to https://issuer.eudiw.dev/ and issue multiple credentials of the same type into your wallet (PID credentials for example)
2. Go to https://verifier.eudiw.dev/ and create a simple credential query (observe the DCQL query by default has no multiple parameter)
3. The wallet presents an UI where it lets the user select claims from multiple credentials (see below)
4. Observe there are multiple credentials in the response on https://verifier.eudiw.dev/ (see below)

DCQL query:

{
  "dcql_query": {
    "credentials": [
      {
        "id": "query_0",
        "format": "dc+sd-jwt",
        "meta": {
          "vct_values": [
            "urn:eudi:pid:1"
          ]
        },
        "claims": [
          {
            "path": [
              "family_name"
            ]
          },
          {
            "path": [
              "given_name"
            ]
          }
        ]
      }
    ]
  },
  "nonce": "f3278647-32ce-40f2-88b3-50485e32011f",
  "request_uri_method": "get",
  "profile": "haip",
  "authorization_request_uri": "haip-vp://"
}
