Allow defining type for getQuery() function via generic

[DeepKumbhare85]

Describe the feature

In server API When we use getQuery() function to parse params from query, it provides type as QueryValue | QueryValue[].
It would be great if we could provide types to this params.

check below code snippet.

export default defineEventHandler((event) => {
    const queries = getQuery(event)
	const searchQuery = queries.q
}

here the type of searchQuery is QueryValue | QueryValue[], but I want type to be string | undefined.It would be great If I could narrow down type to string | undefined.currently I am providing types using typeof for every param.
