There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.
An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);
Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.
The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;
2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;
3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);
4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}
For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

Update the BDS frontpage to pull the RAM ranges from the
smbios extended size fields when applicable. The RAM calculation
also needs to take into account all the RAM ranges being provided
as many machines have multiple physical address ranges.

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.

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.
