[wasm][debugger] Clear valuetypes cache on Debugger.resume (#19778)

* [wasm][debugger] Clear valuetypes cache on Debugger.resume

- This fixes:
	1. Check valuetype properties
	2. Debugger.resume, over some code that updates that valuetype
	3. That valuetype's properties show older values

* [wasm][debugger] Send mono_wasm_debugger_resume only if stopped on

.. a managed frame.
