Add `useMediaQuery` composable

[TylerAPfledderer]

Feature request

Add the useMediaQuery composable to the Vue package.

This is an existing function in the React package to track state of a given CSS media query.

Note: In the React package, it uses a hook called useEnvironment. Need to consider whether or not to also add this as a composable and use it in order to make useMediaQuery workable in these early stages of the Chakra package
See Vue's discussion on Access to Platform Specific APIs in regard to SSR with useEnvironment
