Fix Server Reference being double registered

[shuding]

When we apply createActionProxy twice to the same value, it currently errors because we can't override the ID of it.

This PR makes sure that 1) when the value already have an ID defined, we skip setting it again; 2) all the action IDs are being tracked even for duplicated ones.

Note that it's technically impossible to "detect" the duplication here (via static analyzation) and only set it once. For example:

'use server'

export async function foo () {}
export const bar = a_value_we_dont_know_yet ? foo : async () => {}

So, the compiler will always wrap createActionProxy for every exported value and assume they're different Server Actions (hence different IDs). With this fix, if we find that it's already defined before, we just return the defined reference as they're strictly identical so the ID does't matter.

Closes #54655, closes #61183.

Closes NEXT-2264
