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.

   RAM disk device handle.
3. Install RAM disk configuration form to HII database
