Note: PostingsFormat.forName() does the same lazy-instantiation that the previous impl did

I don't think we should reopen this capability for plugins. It was removed in #8746 and I don't think that the policy should change.
Can we make this change without exposing custom postings format in field mappers ?

I've reworked things so that the MappingLookup detects completion mappers at build time and will return the relevant per-field postings format, removing the pluggability again.

…77234) Currently we configure per-field postings formats by asking the MapperService for the MappedFieldType of the field in question, and then checking to see if it is a completion field. If no MappedFieldType is available, we emit a warning. However, MappedFieldTypes are for search fields only, and so we end up emitting warnings for hidden sub-fields that have no corresponding field type, such as prefix or phrase accelerator fields on text mappers. This commit reworks things so that the MappingLookup is responsible for defining per-field postings formats, and will detect CompletionFieldMappers at build time. All fields that are not mapped to a completion field will just get the default postings format. This also means that we no longer need a logger instance on CodecService. Fixes #77183

Currently we configure per-field postings formats by asking the MapperService
for the MappedFieldType of the field in question, and then checking to see if it
is a completion field. If no MappedFieldType is available, we emit a warning.
However, MappedFieldTypes are for search fields only, and so we end up emitting
warnings for hidden sub-fields that have no corresponding field type, such as
prefix or phrase accelerator fields on text mappers.
This commit reworks things so that the MappingLookup is responsible for defining
per-field postings formats, and will detect CompletionFieldMappers at build time.
All fields that are not mapped to a completion field will just get the default postings
format. This also means that we no longer need a logger instance on CodecService.
