Hao Wu 5cf8a917bd MdeModulePkg RamDiskDxe: Do not save 'Size' numeric value by varstore
The 'Size' numeric value used when creating a raw RAM disk does not
require a varstore to save its previous value in the create raw RAM disk
HII page.

The expecting behavior is that after a user created a raw RAM disk, the
next time when the create raw RAM disk page is entered, the 'Size' numeric
will be the default value (EFI_PAGE_SIZE).

Hao Wu 09abc63675 MdeModulePkg RamDiskDxe: Fix wrong HII behavior for more than 8 RAM disks
The RamDiskDxe driver originally uses a variable-length HII varstore to
retrieve the HII checkbox status of each registered RAM disk.

However, HII does not support the variable-length varstore feature.
Therefore, only the checkbox status for the first 8 RAM disks are tracked
for the following definition of HII varstore structure considering the
alignment:

typedef struct {
  UINT64    Size;
  UINT8     RamDiskList[0];
  } RAM_DISK_CONFIGURATION;

This commit uses the private data of each registered RAM disks to track
the HII checkbox status instead to resolve the issue.
