gpui: Add `cx.intercept_keystrokes` API to intercept keystrokes before action dispatch (#34084)

Closes #ISSUE

`cx.intercept_keystrokes` functions as a sibling API to
`cx.observe_keystrokes`. Under the hood the two API's are basically
identical, however, `cx.observe_keystrokes` runs _after_ all event
dispatch handling (including action dispatch) while
`cx.intercept_keystrokes` runs _before_. This allows for
`cx.stop_propagation()` calls within the `cx.intercept_keystrokes`
callback to prevent action dispatch.

The motivating example usage behind this API is also included in this
PR. It is used as part of a keystroke input component that needs to
intercept keystrokes before action dispatch to display them.
