[performance] refactoring + add fave / follow / request / visibility caching (#1607)

* refactor visibility checking, add caching for visibility

* invalidate visibility cache items on account / status deletes

* fix requester ID passed to visibility cache nil ptr

* de-interface caches, fix home / public timeline caching + visibility

* finish adding code comments for visibility filter

* fix angry goconst linter warnings

* actually finish adding filter visibility code comments for timeline functions

* move home timeline status author check to after visibility

* remove now-unused code

* add more code comments

* add TODO code comment, update printed cache start names

* update printed cache names on stop

* start adding separate follow(request) delete db functions, add specific visibility cache tests

* add relationship type caching

* fix getting local account follows / followed-bys, other small codebase improvements

* simplify invalidation using cache hooks, add more GetAccountBy___() functions

* fix boosting to return 404 if not boostable but no error (to not leak status ID)

* remove dead code

* improved placement of cache invalidation

* update license headers

* add example follow, follow-request config entries

* add example visibility cache configuration to config file

* use specific PutFollowRequest() instead of just Put()

* add tests for all GetAccountBy()

* add GetBlockBy() tests

* update block to check primitive fields

* update and finish adding Get{Account,Block,Follow,FollowRequest}By() tests

* fix copy-pasted code

* update envparsing test

* whitespace

* fix bun struct tag

* add license header to gtscontext

* fix old license header

* improved error creation to not use fmt.Errorf() when not needed

* fix various rebase conflicts, fix account test

* remove commented-out code, fix-up mention caching

* fix mention select bun statement

* ensure mention target account populated, pass in context to customrenderer logging

* remove more uncommented code, fix typeutil test

* add statusfave database model caching

* add status fave cache configuration

* add status fave cache example config

* woops, catch missed error. nice catch linter!

* add back testrig panic on nil db

* update example configuration to match defaults, slight tweak to cache configuration defaults

* update envparsing test with new defaults

* fetch followingget to use the follow target account

* use accounnt.IsLocal() instead of empty domain check

* use constants for the cache visibility type check

* use bun.In() for notification type restriction in db query

* include replies when fetching PublicTimeline() (to account for single-author threads in Visibility{}.StatusPublicTimelineable())

* use bun query building for nested select statements to ensure working with postgres

* update public timeline future status checks to match visibility filter

* same as previous, for home timeline

* update public timeline tests to dynamically check for appropriate statuses

* migrate accounts to allow unique constraint on public_key

* provide minimal account with publicKey
