ipa: rpi: denoise: Support different denoise configurations

Some use cases may require stronger, or different, denosie settings to
others. For example, the way frames are accumulated during single
exposure HDR means that we may want stronger denoise.

This commit adds such support for different configurations that can be
defined in the tuning file.

Older tuning files, or files where there is only a single
configuration, load only the "normal" denoise configuration.
