fix: allow use default factory for primitive types

[cawa-93]

Fix #5938

[yyx990803]

I don't think this fix is right - the resulting inferred type of id will be () => string instead of string: https://www.typescriptlang.org/play?#code/CYUwxgNghgTiAEAXAngBwQOQPaIKoDtQAzAS3xGAB4AVAPngF55r4QAPREQgZ3gFdCIUuWDwA-PHIA3EDHgAuZgG4AsACh160JFgIU6eAEl8RWQBEhUPhESUACgBpm9Ji3acek6xHgAfLwC2AEayfvDciDBkAOZhQVhYECBQ+GHcyMGJYQBiAmCIJFipEiz+ABRlqDBYqNyKdgCUjPTUTYqV1bX1TQwtqhpq2tBwSGgIxqYwFkRWNtw0LvAA3urwa-AA2gDS8GTwANYgyFhEzAC6YooT5pbWttRO2HiCwhQ022e0tP0Avv1a4GGejG8DsnW4AHUSIgABbTWaIeYAISg3BATnhd24ixRaPgADJlqt1ttdqlDsdTpi5mdFDt3FxgLwKSd4LiEBIngRiGQ3uyPvRFNJZL9-oNAbp4EQ8gUivAAO7QuG3Ob2cEYlWI1gcRm8a5TTXzME1bG0Dom+rq+DEBF1eDUxENS0mqGwh1Gq3u76aNTsVBYGCIa0SkbS-D5QqpHnkY21GhjWPYspO+AAJWSwCKEGQ8fQie9Ax9AHoi-AAMJYAL+8j4RAAOikfBAPrInBgMzACETRLUaxIwEu4UiMXUP2J6jARQi8CqJsYCqV7rK0ZAibVJrNDScK17u2A7R69AAslBYXWYClMwFk3XEFgAMrD-DRMoAZgAbA069wICRO2UACYGlHBogA

I'm sorry, but what do you mean? As far as I can see the type for props.id is displayed as a string. Just like derivation for non-primitive types https://www.typescriptlang.org/play?#code/CYUwxgNghgTiAEAXAngBwQOQPaIKoDtQAzAS3xGAB4AVAPngF55r4QAPREQgZ3gFdCIUuWDwA-PHIA3EDHgAuZgG4AsACh160JFgIU6eAEl8RWQBEhUPhESUACgBpm9Ji3acek6xHgAfLwC2AEayfvDciDBkAOZhQVhYECBQ+GHcyMGJYQBiAmCIJFipEiz+ABRlqDBYqNyKdgCUjPTUTYqV1bX1TQwtqhpq2tBwSGgIxqYwFkRWNtw0LvAA3urwa-AA2gDS8GTwANYgyFhEzAC6YooT5pbWttRO2HiCwhQ022e0tP0Avv1a4GGejG8DsnW4AHUSIgABbTWaIeYAISg3BATnhd24ixRaPgADJlqt1ttdqlDsdTpi5mdFDt3FxgLwKSd4LiEBIngRiGQ3uyPvRFNJZL9-oNAbp4EQ8gUivAAO7QuG3Ob2cEYlWI1gcRm8a5TTXzME1bG0Dom+rq+DEBF1eDUxENS0mqGwh1Gq3u76aNTsVBYGCIa0SkbS-D5QqpHnkY21GhjWPYspO+AAJWSwCKEGQ8fQie9Ax9AHoi-AAMJYAL+8j4RAAOikfBAPrInBgMzACETRLUa2iXAAypFLuFIjFibAYIoIlF8NENmdiVgggArRRLEjAadjuc-BzEmfb2fRdQ-YnqMBFCLwKomxgKpXusrRkCJtUms0NJwrXvwfv4Icp3gZNmngABZKBYTrGAUkzAJkzrRAsEAmIygAZgANgaOtuAgEhOzKAAmL8JxgICQN6TYAHIqLOfdf2XNdgJ6egyg3Ld4Bon4SN-Q9OKo08Gh9MMIzlEhuBQucyjtGcYiaJYzwGcTJOic1ajrf9AKEtQS3gAABREAFo-XARBjLIgMb3BOtJ3CGEsGsUQQlHY8F3UZSd1U291MnbTdIM7hjLYdB8nM6o5G87gbLIuyHIgJyEHYo8YkUjzjzUqLGO0tLUMinDIgaIA

Ah ok I got confused myself. Can you add a test case in setupHelpers.test-d.ts?

[PatrickChen928]

I'm confused, why not use
declare type InferDefault<P, T> = T | ((props: P) => T)
instead of
declare type InferDefault<P, T> = T extends null | number | string | boolean | symbol | Function ? T | ((props: P) => T) : (props: P) => T;.
because of never?

According to docs:

Object or array defaults must be returned from a factory function. The function receives the raw props received by the component as the argument.
