ArmPkg/CompilerIntrinsicsLib: provide atomics intrinsics

Gary reports the GCC 10 will emit calls to atomics intrinsics routines
unless -mno-outline-atomics is specified. This means GCC-10 introduces
new intrinsics, and even though it would be possible to work around this
by specifying the command line option, this would require a new GCC10
toolchain profile to be created, which we prefer to avoid.

So instead, add the new intrinsics to our library so they are provided
when necessary.

UefiCpuPkg/MpInitLib: Skip reading PlatformId on AMD processors.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2556

This patch uses CPUID signature check to skip reading the PlatformId MSR,
which is not implemented on AMD processors.

The PlatformId is used for loading microcode patches, which is also not
supported and AMD-based platforms. To mitigate the PlatformId dependency,
PcdCpuMicrocodePatchAddress and PcdCpuMicrodePatchRegionSize must be set
to 0 (default value), in order to bypass microcode loading code paths.

MdeModulePkg/Variable: Initialize local variable "RtPtrTrack"

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2364

Fixes a new build warning in VS2012 introduced in f8ff4cc.

This patch initializes the local variable "RtPtrTrack" in
FindVariableInRuntimeCache ().

This ensures the pointers in the structure are initialized
in the case no variable stores exist in the list of variable
stores.

BaseTools: Fixed regression issue for building !x86 builds

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2134

This patch is to fix a build tool regression issue which
was introduced by commit e8449e1.

In commit e8449e1, build tool check the pcd before
filter out the irrelevant library instance.

The logic of evaluating the priority of the library class
resolutions was not changed.

CryptoPkg/OpensslLib: fix build break caused by missing library

CryptoPkg\Library\Include\CrtLibSupport.h maps strxxxx interfaces to
edk2 PrintLib interfaces but related module inf file don't claim the
use of it. This will cause unresolved symbol issue with VS2017 build
which has enabled strict symbol check. This patch resolves the problem
by adding PrintLib to inf files.

UefiCpuPkg/CommonFeature: Always set FEATURE_CONTROL.Lock

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1305

The patch reverts commit 1ed6498
* UefiCpuPkg/CommonFeature: Skip locking when the feature is disabled

FEATURE_CONTROL.Lock bit is controlled by feature
CPU_FEATURE_LOCK_FEATURE_CONTROL_REGISTER. The commit 1ed649 fixes
a bug that when the feature is disabled, the Lock bit is cleared.
But it's a security hole if the bit is cleared when booting OS.
We can argue that platform needs to make sure the value
of PcdCpuFeaturesUserConfiguration should be set properly to make
sure feature CPU_FEATURE_LOCK_FEATURE_CONTROL_REGISTER is enabled.

But it's better to guarantee this in the generic core code.
