feat: add injectFactory composable

[pikax]

InjectFactory composable

Allows to inject to default to the factory result, instead of default value.

The factory will only be called when the value doesn't exist

Motivation

Sometimes building the defaultValue might be too costly to build every time we want to inject

// normal usage
injectFactory(myKey, ()=> { /* Heavy method */})

// promised based
await injectFactory(myKey, ()=> { /* Promised Heavy method */})
