[pkg/ottl] add User Agent parsing (open-telemetry#34172)

**Description:** <Describe what has changed.>
<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
Added a new ottl converter `UserAgent`: it parses an input string and
matches against a [set of known UA
regexes](https://github.com/ua-parser/uap-core/blob/master/regexes.yaml)
to correctly identify user agent and its version
**Link to tracking Issue:** open-telemetry#32434 

**Testing:** Unit tests, E2E tests

**Documentation:** <Describe the documentation added.> Added UserAgent
description in `pkg/ottl/ottlfuncs/README.md`
