[NTOS:KE][AMD64] Move KD initialization after HalInitializeProcessor call (#9177)

Browse Source 
This is needed for PCI debugging devices whose KD modules depend
on the functions registered in HalpRegisterKdSupportFunctions().

Also it's consistent with what x86 does, and also what Win7 x64 does
(the KdInitSystem is invoked after the HalInitializeProcessor call).

Necessary for PR #9156 on AMD64. CORE-20385
