hv: Other preparation for trampoline code relocation

Browse Source 
- For UEFI boot, allocate memory for trampoline code in ACRN EFI,
  and pass the pointer to HV through efi_ctx
- Correct LOW_RAM_SIZE and LOW_RAM_START in Kconfig and bsp_cfg.h
- use trampline_start16_paddr instead of the hardcoded
  CONFIG_LOW_RAM_START for initial guest GDT and page tables
