Respect warningFilter setting from Svelte 5

[ptrxyz]

Description

To my understanding, currently there is no way to configure svelte/valid-compile with anything but either ignore all warnings or none of them using ignoreWarnings setting.

With Svelte 5, we are given the compiler option warningFilter which is meant to be a "unified way to suppress warnings" for all tools. (See sveltejs/language-tools#2559 (comment))

However it seems that eslint-plugin-svelte does use the svelte compiler under the hood and does not read any configs.
Can we get the plugin to also respect said setting?

note: this would be in addition to onwarn to preserve backwards compatibility while still being consistent with other Svelte tooling.
