+ Convert a Null-terminated ASCII hexadecimal string to a value of type UINT64.
+
+ This function returns a value of type UINT64 by interpreting the contents of
+ the ASCII string String as a hexadecimal number. The format of the input ASCII
+ string String is:
+
+ [spaces][zeros][x][hexadecimal digits].
+
+ The valid hexadecimal digit character is in the range [0-9], [a-f] and [A-F].
+ The prefix "0x" is optional. Both "x" and "X" is allowed in "0x" prefix. If "x"
+ appears in the input string, it must be prefixed with at least one 0. The function
+ will ignore the pad space, which includes spaces or tab characters, before [zeros],
+ [x] or [hexadecimal digits]. The running zero before [x] or [hexadecimal digits]
+ will be ignored. Then, the decoding starts after [x] or the first valid hexadecimal
+ digit. Then, the function stops at the first character that is a not a valid
+ hexadecimal character or Null-terminator, whichever on comes first.
+
+ If String has only pad spaces, then 0 is returned.
+ If String has no leading pad spaces, leading zeros or valid hexadecimal digits, then
+ 0 is returned.
+
+ If the number represented by String overflows according to the range defined by UINT64,
+ then ASSERT().
+ If String is NULL, then ASSERT().
+ If PcdMaximumAsciiStringLength is not zero,
+ and String contains more than PcdMaximumAsciiStringLength ASCII characters not including
+ the Null-terminator, then ASSERT().
