AndroidBootImgLib allows for platforms to append to kernel command
line but does not allow for the overall kernel command line to go
beyond the limit set by the image header. Address this limitation
by adding a pcd where platform can tell how many extra characters
they expect on their platform in addition to what the image header
specifies.

Curently, AndroidBootImgLib expects input kernel command line
to never exceed 256 unicode characters where the image header
allows for 512 ascii characters. If image header allows 512
ascii characters, similar number of unicode characters should be
allowed at the minimum.

The RealTimeClockLib class header in edk2 mistakenly declares a function
called LibRtcVirtualNotifyEvent(). No component ever calls this function
crossing module boundaries; all RealTimeClockLib instances in edk2 and
edk2-platforms are supposed to register (and do register) their
SetVirtualAddressMap() notification functions.
In particular, VirtualRealTimeClockLib *itself* doesn't even use
LibRtcVirtualNotifyEvent() -- the function is defined with an empty body,
clearly in an understandable, but misguided, attempt, to conform to the
(bogus) library interface. Remove the function.

This patch fixes two issues below:
1. SCT SetTime_Func failures.
- https://github.com/pftf/RPi4/issues/164
2. Using shell time and date commands to set time can't work.
The problem is that gRT->SetTime always returns EFI_INVALID_PARAMETER
error status.
The root cause is that LibSetTime() sets RtcEpochSeconds variable with
inconsistent attributes. One is without EFI_VARIABLE_NON_VOLATILE,
the other one is with EFI_VARIABLE_NON_VOLATILE. That caused that the
variable driver returns EFI_INVALID_PARAMETER. Per UEFI spec, if a
preexisting variable is rewritten with different attributes,
SetVariable() shall not modify the variable and shall return
EFI_INVALID_PARAMETER.
Therefore, the solution is to add EFI_VARIABLE_NON_VOLATILE attribute
to the first EfiSetVariable() call to make two calls consistent.
By the way, this patch also fix a minor issue with a debug message.

The message "LibGetTime: RtcEpochSeconds non volatile variable was not
found - Using compilation time epoch." can be printed a very large
number of times, causing log files to become excessively large. This is
because the RtcEpochSeconds variable only gets set if LibSetTime is
called, for example by running 'time 12:00' in the UEFI Shell.
Avoid this by setting RtcEpochSeconds to BUILD_EPOCH (EpochSeconds)
after printing the message. It's set to a volatile variable so the
message will be displayed on future boots and not hidden.
Commit 44ae214591e58af468eacb7b873eaa0bc187c4fa reduced the verbosity of
the message to DEBUG_VERBOSE. Revert it back to DEBUG_INFO so it's more

Addresses BZ https://bugzilla.tianocore.org/show_bug.cgi?id=2380 where
explicit casts are required for 64 to 32 bit assignment.
We can apply a straight cast for Time->Nanosecond since we already checked
for overflow.
On the other hand, we may have a frequency that is greater than UINT32_MAX
for Capabilities->Resolution. But using the frequency for the resolution
is the wrong approach anyway, since we can't actually vouch for the actual
resolution of the virtual library. Instead, play it safe by defaulting to
1 Hz, which is what a standard PC-AT CMOS RTC device would use.

For the LoadImage() boot service, with EFI_SECURITY_VIOLATION retval,

This follows UEFI Spec.
But if the caller of LoadImage() doesn't have the option to defer
the execution of an image, we can not treat EFI_SECURITY_VIOLATION
like any other LoadImage() error, we should unload image for the
EFI_SECURITY_VIOLATION to avoid resource leak.
This patch is to do error handling for EFI_SECURITY_VIOLATION explicitly
