Reorganise the database schema directories (#9932)

The hope here is that by moving all the schema files into synapse/storage/schema, it gets a bit easier for newcomers to navigate.

It certainly got easier for me to write a helpful README. There's more to do on that front, but I'll follow up with other PRs for that.

--- When we first added the room_version column to the rooms table, it was populated from
--- the current_state_events table. However, there was an issue causing a background
--- update to clean up the current_state_events table for rooms where the server is no
--- longer participating, before that column could be populated. Therefore, some rooms had
--- a NULL room_version.
-
--- The rooms_version_column_2.sql.* delta files were introduced to make the populating
--- synchronous instead of running it in a background update, which fixed this issue.
--- However, all of the instances of Synapse installed or updated in the meantime got
--- their rooms table corrupted with NULL room_versions.
-
--- This query fishes out the room versions from the create event using the state_events
--- table instead of the current_state_events one, as the former still have all of the
--- create events.

-# Synapse Database Schemas
-
-These schemas are used as a basis to create brand new Synapse databases, on both
-SQLite3 and Postgres.
-
-## Building full schema dumps
-
-If you want to recreate these schemas, they need to be made from a database that
-has had all background updates run.
-
-To do so, use `scripts-dev/make_full_schema.sh`. This will produce new
-`full.sql.postgres ` and `full.sql.sqlite` files. 
-
-Ensure postgres is installed and your user has the ability to run bash commands
-such as `createdb`, then call
-
-    ./scripts-dev/make_full_schema.sh -p postgres_username -o output_dir/
-
-There are currently two folders with full-schema snapshots. `16` is a snapshot
-from 2015, for historical reference. The other contains the most recent full
-schema snapshot.
