For pointer subtraction, the result is of type "ptrdiff_t". According to
the C11 standard (Committee Draft - April 12, 2011):
"When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object; the
result is the difference of the subscripts of the two array elements. The
size of the result is implementation-defined, and its type (a signed
integer type) is ptrdiff_t defined in the <stddef.h> header. If the result
is not representable in an object of that type, the behavior is
undefined."
In our codes, there are cases that the pointer subtraction is not
performed by pointers to elements of the same array object. This might
lead to potential issues, since the behavior is undefined according to C11
standard.
Also, since the size of type "ptrdiff_t" is implementation-defined. Some
static code checkers may warn that the pointer subtraction might underflow
first and then being cast to a bigger size. For example:
UINT8 *Ptr1, *Ptr2;
UINTN PtrDiff;
...
PtrDiff = (UINTN) (Ptr1 - Ptr2);
The commit will refine the pointer subtraction expressions by casting each
pointer to UINTN first and then perform the subtraction:
PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2;

Some boot options may be deleted in the "Delete Boot Option page",
But the data BootOptionOrder in BmmFakeNvData may not be updated.
So when user enter the "Change Boot Order" page, we should not always
get the BootOptionOrder in BmmFakeNvData, it will result in incorrect
UI behaviors. When the Boot Options have been saved,
we should get the BootOptionOrder through function GetBootOrder.
For driver option codes need to do the same change.
This patch is to fix the issue in bugzilla:

PcdSet## has no error status returned, then the caller has no idea about whether the set operation is successful or not.
PcdSet##S were added to return error status and PcdSet## APIs were put in ifndef DISABLE_NEW_DEPRECATED_INTERFACES condition.
To adopt PcdSet##S and further code development with DISABLE_NEW_DEPRECATED_INTERFACES defined, we need to Replace PcdSet## usage with PcdSet##S.
Normally, DynamicDefault PCD set is expected to be success, but DynamicHii PCD set failure is a legal case.
So for DynamicDefault, we add assert when set failure. For DynamicHii, we add logic to handle it.

The above using of AllocateCopyPool() will read contents out of the scope

Per UEFI spec, on CallBack action EFI_BROWSER_ACTION_CHANGING, the return value of ActionRequest will be ignored, but on CallBack action EFI_BROWSER_ACTION_CHANGED, the return value of ActionRequest will be used.
But, EDKII browser still processes the got ActionRequest. And, all HII drivers in EDKII project also returns their expected ActionRequest value on action EFI_BROWSER_ACTION_CHANGING.
Now update the browser to follow the spec, and update all core Hii drivers to keep old working modal.
