Begin solid-router and router-core

[Brendonovich]

I've copied react-router into solid-router and replaced most of the React APIs with their Solid equivalent, and also extracted a lot of code that doesn't rely on Solid to router-core, which we can later use in react-router.
solid-router still has a lot of issues (and seems to be running into solidjs/solid#2352), but a high number of tests are already passing.

The render function from @solidjs/testing-library does not update the router state, nor render the route related html elements.
This causes many unit tests to fail.

I'm not sure this is great export * from '@tanstack/router-core'. I assume it's a result of moving the ./history.ts file over, and replacing the export * from './history', but the @tanstack/router-core contain a lot more.

These functions can't be extracted this easily - they depend on the AnyRouter now:

router/packages/react-router/src/routeInfo.ts

Lines 62 to 75 in 255f316

	export type ParentPath<TRouter extends AnyRouter> =
	TrailingSlashOptionByRouter<TRouter> extends 'always'
	? '../'
	: TrailingSlashOptionByRouter<TRouter> extends 'never'
	? '..'
	: '../' | '..'
	export type CurrentPath<TRouter extends AnyRouter> =
	TrailingSlashOptionByRouter<TRouter> extends 'always'
	? './'
	: TrailingSlashOptionByRouter<TRouter> extends 'never'
	? '.'
	: './' | '.'

@Brendonovich FYI on the router-core package present on "main" which has centralized some of the sharable parts of packages/react-router.

This is being continued on #3276, I'm happy to have got the ball rolling 😄
