New React DOM Features

browser(): a new react-dom API that returns a usable which errors during server rendering and resolves in the browser. use(browser()) inside a <Suspense> boundary marks a subtree as browser-only without reporting a recoverable error (@gnoff: #37143, #37241)

Added an onBrowserBailout option to the react-dom/server APIs to observe when a subtree defers to the browser (@gnoff #37193)

Notable changes

Enable Trusted Types API integration (@rickhanlonii #35816)

Transitions now render independently instead of being entangled into a single render, so a slow transition no longer holds up unrelated ones (@acdlite #37290)

Added a DEV-only warning when a component appears to have been unblocked by calling use() conditionally (@hoxyq, @eps1lon: #37104, #37203, #37491)
