Payload is designed with performance in mind, but its customizability
means that there are many ways to configure your app that can impact
performance.
While Payload provides several features and best practices to help you
optimize your app's specific performance needs, these are not currently
well surfaced and can be obscure.
Now:
- A high-level performance doc now exists at `/docs/performance`
- There's a new section on performance within the `/docs/queries` doc
- There's a new section on performance within the `/docs/hooks` doc
- There's a new section on performance within the
`/docs/custom-components` doc
This PR also:
- Restructures and elaborates on the `/docs/queries/pagination` docs
- Adds a new `/docs/database/indexing` doc
- More

It is a common pattern to dynamically show and validate a select field's
options based on various criteria such as the current user or underlying
document.
Some examples of this might include:
- Restricting options based on a user's role, e.g. admin-only options
- Displaying different options based on the value of another field, e.g.
a city/state selector
While this is already possible to do with a custom `validate` function,
the user can still view and select the forbidden option...unless you
_also_ wired up a custom component.
Now, you can define `filterOptions` on select fields.
This behaves similarly to the existing `filterOptions` property on
relationship and upload fields, except the return value of this function
is simply an array of options, not a query constraint. The result of
this function will determine what is shown to the user and what is
validated on the server.
Here's an example:
```ts
{
name: 'select',
type: 'select',
options: [
{
label: 'One',
value: 'one',
},
{
label: 'Two',
value: 'two',
},
{
label: 'Three',
value: 'three',
},
],
filterOptions: ({ options, data }) =>
data.disallowOption1
? options.filter(
(option) => (typeof option === 'string' ? options : option.value) !== 'one',
)
: options,
}
```
Continuation of #10741. Field-level admin options, including the
conditional logic and custom field components, are currently documented
within the "admin > customizing views" page. This makes them hard to
find because users, myself included, intuitively navigate to the fields
overview doc first to locate this information. Now, they are rendered
within "fields > overview" as expected. This should help keep the user
from jumping around from doc to doc and getting lost.
Although the "customizing fields" doc provides a big picture overview of
how to create custom field components, it is not explicit enough for
developers to know exactly where to start. For example, it can be
challenging to import the correct types when building these components,
and the natural place to go looking for this information is on the
fields docs themselves. Now, each field doc has its own dedicated
"custom components" section which provides concrete examples for fields
and field labels in both server and client component format, with more
examples to come over time such as using inputs directly, etc. In the
same vein, the "customizing fields" doc itself should probably be moved
to the fields overview section so it remains as intuitive as possible
when searching for this information.

## Description
Adds `virtual` property to the fields config. Providing `true`
completely disables the field in the DB, which is useful for [Virtual
Fields](https://payloadcms.com/blog/learn-how-virtual-fields-can-help-solve-common-cms-challenges)
Disables abillity to query by a field with `virtual: true`.
Currently, they bloat the DB with unused tables / columns, which may as
well introduce additional joins.
