event listeners need to support bypassing modality checks

[mstahv]

Description of the bug

Events are a way more powerful mechanism to send data from client to the server. For example supporting debouncing etc. Sinse the server side modality changes, this is handicapped for certain scenarios, where events are not actual component events but somethign regarding browser/ui level. Like geolocation API, browser window size etc.

Expected behavior

The API should support allowInert() or similar annotation to bypass the checks for selected events.

Minimal reproducible example

Check the hacks needed for Viritin's geolocation API to work when a dialog is open.

Versions

• Vaadin / Flow version: 24.3

Created a draft PR. Would still need some unit tests, but actual functionality tested manually with/in #19122
