HV: correct ept page array usage

Browse Source 
Currently ept_pages_info[] is initialized with first element only that force
VM of id 0 using SOS EPT pages. This is incorrect for logical partition and
hybrid scenario. Considering SOS_RAM_SIZE and UOS_RAM_SIZE are configured
separately, we should use different ept pages accordingly.

So, the PRE_VM_NUM/SOS_VM_NUM and MAX_POST_VM_NUM macros are introduced to
resolve this issue. The macros would be generated by acrn-config tool when
user configure ACRN for their specific scenario.

One more thing, that when UOS_RAM_SIZE is less then 2GB, the EPT address
range should be (4G + PLATFORM_HI_MMIO_SIZE).

Tracked-On: #4458
