[Patch 00/10 V5] Enable multiple process AutoGen

["Bob Feng" <bob.c.feng@intel.com>]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1875

In order to improve the build performance, we implemented
multiple-processes AutoGen. This change will reduce 20% time
for AutoGen phase.

The design document can be got from:
https://edk2.groups.io/g/devel/files/Designs/2019/0627/Multiple-thread-AutoGen.pdf

This patch serial pass the build of Ovmf, MinKabylake, MinPurley, packages
under Edk2 repository and intel client and server platforms.

V5:
Restructure the patches of V4. Squash 11/11 patch of V4 into V5 4/10,
5/10 and 10/10.

The details of the changes are as following:

1. Update Log queue maxsize as the value of thread number * 10.
This change is implemented in patch 10/10

2. Fixed the regression issue that the PCDs from build command line
are not passed into autogen sub-process correctly.

3. Fixed the regression issue that the exception raised inside
autogen sub-process is not well handled, including code exception
and Ctrl+C keyboard interrupt.

The above 2 changes are implemented in patch 5/10

4. Fixed the regression issue that multiple builds of the same 
driver/application with FILE_GUID overrides is not handle correctly.

5. Fixed the regression issue that shared fixed PCD between lib
and module is not handle correctly, which cause the autogen.c and 
autogen.h are different from orignal.

The above 2 changes are implemented in patch 4/10

V4:
Add one more patch 11/11 to enhance this feature. 1-10 are the same as V3
1. Set Log queue maxsize as thread number * 10
2. enhance ModuleUniqueBaseName function
3. fix bugs of build option pcd in sub Process
4. enhance error handling. Handle the exception of
KeyboardInterrup and exceptions happen in subprocess.
5. fix the issue of shared fixed pcd between module and lib.
6. fix bug in the function of duplicate modules handling.
V3:
1. Fixed incremental build issue.
2. Set AutoGen worker number to be align with "-n THREADNUMBER"
3. Enable block log queue.
V2: 
1. The first version missed autogen related commit 
from e812a812c1a0800c49e11507cb46222351520cc7. V2 add those commit
back.
2. Move CreateAsBuildInf into AutoGenWorker process
3. Save GlobalVar_<platform guid>_<arch>.bin to build folder.
4. Regenerate patches based on master bb824f685d
