libcbor: updated to 0.11.0

0.11.0 (2024-02-04)
---------------------
- [Updated documentation to refer to RFC 8949](https://github.com/PJK/libcbor/issues/269)
- Improvements to `cbor_describe`
  - [Bytestring data will now be printed as well](https://github.com/PJK/libcbor/pull/281) by  [akallabeth](https://github.com/akallabeth)
  - [Formatting consistency and clarity improvements](https://github.com/PJK/libcbor/pull/285)
- [Fix `cbor_string_set_handle` not setting the codepoint count](https://github.com/PJK/libcbor/pull/286)
- BREAKING: [`cbor_load` will no longer fail on input strings that are well-formed but not valid UTF-8](https://github.com/PJK/libcbor/pull/286)
  - If you were relying on the validation, please check the result using `cbor_string_codepoint_count` instead
- BREAKING: [All decoders like `cbor_load` and `cbor_stream_decode` will accept all well-formed tag values](https://github.com/PJK/libcbor/pull/308) (bug discovered by [dskern-github](https://github.com/dskern-github))
  - Previously, decoding of certain values would fail with `CBOR_ERR_MALFORMATED` or `CBOR_DECODER_ERROR`
  - This also makes decoding symmetrical with serialization, which already accepts all values
