[APMSP-1764] Support borrowed buffer for msgpack decoding

[anais-raison]

What does this PR do?

Use &[u8] in the msgpack decoder instead of Bytes and produce a SpanSlice which contains &str instead of BytesString. This allows to parse non-owned buffer containing traces. It also provides a from_bytes wrapper which uses the same parsing logic but convert the &str to BytesString based on the given Bytes buffer.

Motivation

The trace exporter needs to support reading traces from borrowed buffer.

Additional Notes

This PR also refactors the string, map and number decoding logic to be moved to separate modules.

How to test the change?

Describe here in detail how the change can be validated.
