Styles API (#1580)
Removes `propsForNextShape` and replaces it with the new styles API. 

Changes in here:
- New custom style example
- `setProp` is now `setStyle` and takes a `StyleProp` instead of a
string
- `Editor.props` and `Editor.opacity` are now `Editor.sharedStyles` and
`Editor.sharedOpacity`
- They return an object that flags mixed vs shared types instead of
using null to signal mixed types
- `Editor.styles` returns a `SharedStyleMap` - keyed on `StyleProp`
instead of `string`
- `StateNode.shapeType` is now the shape util rather than just a string.
This lets us pull the styles from the shape type directly.
- `color` is no longer a core part of the editor set on the shape
parent. Individual child shapes have to use color directly.
- `propsForNextShape` is now `stylesForNextShape`
- `InstanceRecordType` is created at runtime in the same way
`ShapeRecordType` is. This is so it can pull style validators out of
shape defs for `stylesForNextShape`
- Shape type are now defined by their props rather than having separate
validators & type defs

### Change Type

- [x] `major` — Breaking change

### Test Plan

1. Big time regression testing around styles!
2. Check UI works as intended for all shape/style/tool combos

- [x] Unit Tests
- [ ] End to end tests

### Release Notes

@tldraw/tlschema

This package houses type definitions, schema migrations, and other type metadata for the tldraw editor's default persisted data.

There are three main kinds of types:

  • Record types

    These are root record types added to the Store class. They are defined in the ./src/records directory.

  • Shape types

    These are subtypes of the root TLShape record type. They allow specifying a unique name and custom props for a particular kind of shape.

  • Asset types

    These are subtypes of the root TLAsset record type. They allow specifying a unique name and custom props for a particular kind of asset.

Adding migrations

If you make any kind of change to any persisted data shape in this package, you must add migrations that are able to convert old versions to new versions, and vice-versa.

If you are making a change that affects the structure of a record, shape, or asset, update the migrations in the same file as the record, shape, or asset is defined.

If you are making a change that affects the structure of the store (e.g. renaming or deleting a type, consolidating two shape types into one, etc), add your changes in the migrations in schema.ts.

After making your changes, add a new version number, using a meaninful name. For example, if you add a new property to the TLShape type called ownerId that points to a user, you might do this:

In TLShape.ts

 const Versions = {
   RemoveSomeProp: 1,
+  AddOwnerId: 2,
 } as const

and then in the TLShape type

   x: number
   y: number
+  ownerId: ID<TLUser> | null
   props: Props
   parentId: ID<TLShape> | ID<TLPage>

and then adding a migration:

 export const shapeTypeMigrations = defineMigrations({
   currentVersion: Versions.Initial,
   firstVersion: Versions.Initial,
   migrators: {
+    [Versions.AddOwnerId]: {
+      // add ownerId property
+      up: (shape) => ({...shape, ownerId: null}),
+      // remove ownerId property
+      down: ({ownerId, ...shape}) => shape,
+    }
   },

After you've added your migration, make sure to add a test for it in src/migrations.test.ts. It will complain if you do not!
