fix: avoid relying on Function.prototype.name to detect react components (#13931)

### What

Remove references to the `.name` property in the logic for detecting
react components. Instead just rely on `typeof` and `length`.

### Why

Don't use the presence/absence of function names to detect react
components or to distinguish client vs server components.

minifiers generally do not preserve function names. e.g. in swc
[`keepFnNames` is false by
default](https://swc.rs/docs/configuration/minification#:~:text=with%20terser.-,keepFnNames,-%2C%20Defaults%20to%20false).

A recent
[PR](ba227046ef)
in Next.js optimized the representation of esm exports which meant that
many `export function Foo` declarations would loose their names. This
broke users of payloadcms since now server props were no longer
propagated to their components due to the check
[here](c2300059a6/packages/ui/src/elements/withMergedProps/index.tsx (L43)).
