### What?
Adds four more arguments to the `mongooseAdapter`:
```typescript
useJoinAggregations?: boolean /* The big one */
useAlternativeDropDatabase?: boolean
useBigIntForNumberIDs?: boolean
usePipelineInSortLookup?: boolean
```
Also export a new `compatabilityOptions` object from
`@payloadcms/db-mongodb` where each key is a mongo-compatible database
and the value is the recommended `mongooseAdapter` settings for
compatability.
### Why?
When using firestore and visiting
`/admin/collections/media/payload-folders`, we get:
```
MongoServerError: invalid field(s) in lookup: [let, pipeline], only lookup(from, localField, foreignField, as) is supported
```
Firestore doesn't support the full MongoDB aggregation API used by
Payload which gets used when building aggregations for populating join
fields.
There are several other compatability issues with Firestore:
- The invalid `pipeline` property is used in the `$lookup` aggregation
in `buildSortParams`
- Firestore only supports number IDs of type `Long`, but Mongoose
converts custom ID fields of type number to `Double`
- Firestore does not support the `dropDatabase` command
- Firestore does not support the `createIndex` command (not addressed in
this PR)
### How?
```typescript
useJoinAggregations?: boolean /* The big one */
```
When this is `false` we skip the `buildJoinAggregation()` pipeline and resolve the join fields through multiple queries. This can potentially be used with AWS DocumentDB and Azure Cosmos DB to support join fields, but I have not tested with either of these databases.
```typescript
useAlternativeDropDatabase?: boolean
```
When `true`, monkey-patch (replace) the `dropDatabase` function so that
it calls `collection.deleteMany({})` on every collection instead of
sending a single `dropDatabase` command to the database
```typescript
useBigIntForNumberIDs?: boolean
```
When `true`, use `mongoose.Schema.Types.BigInt` for custom ID fields of type `number` which converts to a firestore `Long` behind the scenes
```typescript
usePipelineInSortLookup?: boolean
```
When `false`, modify the sortAggregation pipeline in `buildSortParams()` so that we don't use the `pipeline` property in the `$lookup` aggregation. Results in slightly worse performance when sorting by relationship properties.
### Limitations
This PR does not add support for transactions or creating indexes in firestore.
### Fixes
Fixed a bug (and added a test) where you weren't able to sort by multiple properties on a relationship field.
### Future work
1. Firestore supports simple `$lookup` aggregations but other databases might not. Could add a `useSortAggregations` property which can be used to disable aggregations in sorting.

This PR allows to have full type safety on `payload.drizzle` with a
single command
```sh
pnpm payload generate:db-schema
```
Which generates TypeScript code with Drizzle declarations based on the
current database schema.
Example of generated file with the website template:

We also now proxy drizzle package the same way we do for Lexical so you
don't have to install it (and you shouldn't because you may have version
mismatch).
Instead, you can import from Drizzle like this:
```ts
import {
pgTable,
index,
foreignKey,
integer,
text,
varchar,
jsonb,
boolean,
numeric,
serial,
timestamp,
uniqueIndex,
pgEnum,
} from '@payloadcms/db-postgres/drizzle/pg-core'
import { sql } from '@payloadcms/db-postgres/drizzle'
import { relations } from '@payloadcms/db-postgres/drizzle/relations'
```
Fixes https://github.com/payloadcms/payload/discussions/4318
In the future we can also support types generation for mongoose / raw
mongodb results.
