The ShellCommandRunSetVar() function calls the ShellIsHexOrDecimalNumber()
UefiShellLib function to determine if the data string in the SETVAR
command is a string of hexadecimal bytes.
However, ShellIsHexOrDecimalNumber() calls ShellConvertStringToUint64()
for validation. Therefore SETVAR rejects hex strings that cannot be
interpreted as UINT64 values due to range errors, despite the fact that
the hexadecimal data string of the SETVAR command is supposed to describe
an arbitrary array of bytes, rather than UINT64 values.
The internal library function InternalShellIsHexOrDecimalNumber() comes
close, as the first idea for the fix, however it is not quite right
either; it removes a leading minus sign, plus it allows 0x / 0X prefixes.
This would not be correct for the SETVAR command.
Instead, add a trivial utility function that is specific to the SETVAR
implementation. IsStringOfHexNibbles() accepts empty strings for
simplicity, but where we call it we have already ensured that the data
string is not empty (because that is handled earlier by the "delete
variable" branch of SETVAR). An even number of nibbles is also enforced
near the call site.

It's invalid to set a variable that's available from runtime services but not
from boot services.
Currently if you pass '-rt' without '-bs' you get a generic
'Invalid Parameter' message. We should either print a more useful message in
this case, or make '-rt' imply '-bs' (as this patch does). The Shell Spec is
ambiguous on the matter.

If AllocateZeroPool() returns NULL,
GetVariable() will return EFI_BUFFER_TOO_SMALL,
FreePool() will receive NULL.
So check for NULL before FreePool().
