fix(clerk-react,tanstack): TanStack Start loaders running twice and hydration issues due to Clerk resolved

[kaandok]

Description

• Removes unnecessary router.load() in middlewareHandler.ts which is causing router to re-run processing. This was originally proposed in Fix Tanstack Start Context Corruption and stop loaders from re-running. #4414 by @phibr0 but got reverted in dac21ed. It is still a problem and needs the fix.
• Wraps state updates in ClerkContextProvider.tsx with React.startTransition so server side rendered pages do not have hydration issues.

Checklist

• pnpm test runs as expected.
• pnpm build runs as expected.

Type of change

• 🐛 Bug fix
