apigatewayv2: Retry on ConflictException: Unable to complete operation due to concurrent modification errors

[ewbankkit]

Description

Restores the service-wide retry on ConflictException removed during AWS SDK for Go v2 migration (#36490).
Consciously retains the change made in #37732 as that also adds a custom timeout to a single resource's delete.

Relations

Closes #37897.
