Rename config types

[TelepathicGrunt]

Continuation of neoforged/FancyModLoader#436

SERVER -> SYNCED
COMMON -> LOCAL

The idea here is making it clear that the was SERVER configs are synced between client and server (with the comment on it > explaining the sync direction). And changing COMMON to LOCAL makes it clears COMMON is not a synced config. Rather just a regular default standard config with no sync involved.

Changes were limited to renames to keep PR as small as possible. Any alternative names will need a very strong reason to convince me to change it.

If you wish for a different setup such as sync-ness as part of the config setup or removal of an entire config type, please make a separate PR and post it in comment here so implementations can be judged. Also helps to reduce bikeshedding by pushing forth a "less-talking, more-doing" stance to this.

Ideally we would target 26.3 for this. Once merged, NeoForge will get a PR to use new FML and make the same config name changes (including to the config files and folders to match new name).

This is a large scale breaking change and will need a dev announcement when NeoForge updates.

Closes: neoforged/FancyModLoader#276

NOTE: Do not release with the experimental FML lines. Revert that commit and update to newly released FML once the relevant PR is merged and 26.3 is out. Be sure to retarget this branch to 26.3 and undraft
