Jeremy Apthorp 805a55099b test: tsify more web contents specs (#19969)
* test: tsify more WebContents specs

* getFocusedWebContents

* setDevToolsWebContents, isFocused, isCurrentlyAudible

* getWebPreferences, openDevTools

* before-input-event

* zoom-changed

* sendInputEvent

* insertCSS

* startDrag

* focus, getOSProcessId

* zoom api

* more closeAllWindows

* fix detached dev tools test

* fix zoom-changed test

* compare the correct kind of id 🤦‍♂️

* 'fix' openDevTools test to wait for multiple focus events

* fix tests? 🤞

* use request instead of blur to detect openExternal success

* try not timing out the keychain for testing

* use blur event on mac, sigh

* oh, right, still gotta open an actual url
