Sasha 0e5bda9a74 feat: make req partial and optional in DB / Local API operations (#9935)
### What?
Previously, the `req` argument:
In database operations (e.g `payload.db`) was required and you needed to
pass the whole `req` with all the properties. This is confusing because
in database operations we never use its properties outside of
`req.transactionID` and `req.t`, both of which should be optional as
well.

Now, you don't have to do that cast:
```ts
payload.db.findOne({
  collection: 'posts',
  req: {} as PayloadRequest,
  where: {
    id: {
      equals: 1,
    },
  },
})
```
Becomes:
```ts
payload.db.findOne({
  collection: 'posts',
  where: {
    id: {
      equals: 1,
    },
  },
})
```

If you need to use transactions, you're not required to do the `as` cast
as well now, as the `req` not only optional but also partial -
`Partial<PayloadRequest>`.
`initTransaction`, `commitTransaction`, `killTransaction` utilities are
typed better now as well. They do not require to you pass all the
properties of `req`, but only `payload` -
`MarkRequired<Partial<PayloadRequest>, 'payload'>`
```ts
const req = { payload }
await initTransaction(req)
await payload.db.create({
  collection: "posts",
  data: {},
  req
})
await commitTransaction(req)
```

The same for the Local API. Internal operations (for example
`packages/payload/src/collections/operations/find.ts`) still accept the
whole `req`, but local ones
(`packages/payload/src/collections/operations/local/find.ts`) which are
used through `payload.` now accept `Partial<PayloadRequest>`, as they
pass it through to internal operations with `createLocalReq`.

So now, this is also valid, while previously you had to do `as` cast for
`req`.
```ts
const req = { payload }
await initTransaction(req)
await payload.create({
  collection: "posts",
  data: {},
  req
})
await commitTransaction(req)
```


Marked as deprecated `PayloadRequest['transactionIDPromise']` to remove
in the next major version. It was never used anywhere.
Refactored `withSession` that returns an object to `getSession` that
returns just `ClientSession`. Better type safety for arguments
Deduplicated in all drizzle operations to `getTransaction(this, req)`
utility:
```ts
const db = this.sessions[await req?.transactionID]?.db || this.drizzle
```
Added fallback for throwing unique validation errors in database
operations when `req.t` is not available.

In migration `up` and `down` functions our `req` is not partial, while
we used to passed `req` with only 2 properties - `payload` and
`transactionID`. This is misleading and you can't access for example
`req.t`.
Now, to achieve "real" full `req` - we generate it with `createLocalReq`
in all migration functions.

This all is backwards compatible. In all public API places where you
expect the full `req` (like hooks) you still have it.

### Why?
Better DX, more expected types, less errors because of types casting.
