Consider deprecating MediaQuery in favor of Svelte's implementation

Proposed Changes

Considering that Svelte now has its own reactive MediaQuery class built in, I'm not sure if it's necessary maintaining a userland implementation other than for backwards compat.

The only thing missing is the ability to pass in a function, but in my opinion, I don't think this is really a dealbreaker.
