feat: Set otel_logging_supported_config to true when otlp receiver is enabled for logs. Fix extension ordering in config

[XuechunHou]

Description

1. Set otel_logging_supported_config to true in Feature Tracking when OTLP receiver is enabled via a combined field to collect OTLP logs using OTel.
2. Sort extension list in the generated otel.yaml, this avoids flakiness in confgenerator tests when multiple extensions are specified (e.g: filestorage, and gogleclientauth)

LGTM modulo addressing the comments. Nit: Update PR description to a simplified explanation of the change.
