Support per-attempt timeout configuration

[ianbotsf]

Describe the feature

The Kotlin SDK does not presently support per-attempt timeouts, although other SDKs such as Java v2 and Rust do. Design and implement new config parameter(s) to support this.

Consider also whether a dedicated request-level timeout setting would also be helpful. Users can implement their own guards using kotlinx.coroutines's withTimeout function but a native config param is likely more expected from other SDKs and allows more centralized control of timeouts.

Is your feature request related to a problem?

Users currently have no way to limit attempt duration and can only control overall request duration via withTimeout.
