Close the ReadyToBoot and ExitBootServices events in the reset notification. This prevents the file logger from trying to access the file system after its reset notification has run in the event that the platform implementation invokes one of those notifications in the reset path (which it shouldn't, but some do).
Executed reset, confirmed that file log is flushed as expected. On a system that also invokes the exit boot services notification in the reset path, confirmed that log file is not flushed in the exit boot services notification. Confirmed that on normal boot path to OS, log flush is executed in the exit boot path notification.

Added logic to delete the Memory Type Information variable on a capsule update. This is because in rare circumstance where a new memory type is added (or a memory type is removed) a capsule update will cause a mismatch of memory types. Removing the variable and thus forcing a clean memory bucket discovery solves this issue.
For each item, place an "x" in between [
and ]
if true. Example: [x]
.

Tested on a platform where there is a capsule update between two versions of firmware with a different amount of memory types. Without this change the transition from temp ram to permanent memory breaks but with this change the device correctly goes to the default memory bucket configuration and is able to boot.

AdvLoggerSerialPortLib was using a library class that was not a true library class (not defined in any .dec file or have an associated .h).
This changes the library class to use the correct library class, SerialPortLib.
Successfully build multiple platforms and pass the newly added BaseTools change for verifying library override class names.
Any library class definitions in a dsc using AdvLoggerSerialPortLib needs to be switched to SerialPortLib.

This change added a few new matrix entries to support building mu_tiano_platforms on native ARM64 systems. The PR will cover both https://github.com/microsoft/mu_basecore/issues/369 and https://github.com/microsoft/mu_basecore/issues/305.
The PR should also be incorporated with mu_devops change.

This was tested on selfhost-agents and existing agents.
Pipeline changes, N/A for integration.

Cherry picks commits from PR #259 into release/202208 into release/202302.
Some platforms may not reach BDS on a boot mode expected by the
current implementation to update the ConIn variable with a new
console input device.
For example, support for a new device might be added in a firmware
update, the update is performed, and the system is reset one or
more times before reaching PlatformBootManagerBeforeConsole().
This change always evaluates a potential update to ConIn regardless
of boot mode to reduce ConIn update complexity.
Verified the build and boot with the change. Since only the boot mode check
is removed, the underlying behavior within the boot mode condition remains
the same
Review the change to when console may be updated relative to boot mode in
change and the implementation of EfiBootManagerUpdateConsoleVariable()
being used by the platform to determine if you would like to make any
changes to that function. No required changes are expected.

This is the first MU Plus 202302 release 🎉
The previous branch was 202208.
These versions correspond to edk2 stable release tags that the code is based upon.
Since edk2 makes a release every 3 months, two stable tags were actually picked up in this release:
Review those release notes to understand the changes coming in from edk2. In addition, Mu repos highlight important changes in their Readme files. Review the 202302 Readme before you move code to this branch to understand major changes.
