[libcamera-devel] [RFC PATCH 6/7] libcamera: pipeline: simple: rename converterBuffers_ and related vars

The converterBuffers_ and the converterQueue_ are not that specific
to the Converter, and could be used by another entity doing the format
conversion.
Rename converterBuffers_, converterQueue_, and useConverter_ to
conversionBuffers_, conversionQueue_ and useConversion_ to
disassociate them from the Converter.
