win32u: Avoid calling WH_CBT HCBT_CLICKSKIPPED hooks recursively.

Browse source 
Previously, accept_hardware_message() is called after WH_CBT HCBT_CLICKSKIPPED hooks. So when
these hooks call PeekMessage(), they will be called recursively. Note that WH_MOUSE hooks do
get called recursively according to tests.
