Liming Gao 1ccc4d895d Revert BaseTools: PYTHON3 migration
This reverts commit 6693f359b3c213513c5096a06c6f67244a44dc52..
678f851312.

Python3 migration is the fundamental change. It requires every developer
to install Python3. Before this migration, the well communication and wide
verification must be done. But now, most people is not aware of this change,
and not try it. So, Python3 migration is reverted and be moved to edk2-staging
Python3 branch for the edk2 user evaluation.

Gary Lin 7de0083812 BaseTools: Move ImageBinDict to GenFdsGlobalVariable.py
Move "ImageBinDict" from GenFds.py to GenFdsGlobalVariable.py so that we
can remove the requirement to import GenFds.GenFds in Capsule.py, Fd.py and
Fv.py. This breaks the following circular imports:

* GenFds.FdfParser => GenFds.Capsule => GenFds.GenFds => GenFds.FdfParser
* GenFds.FdfParser => GenFds.Fd => GenFds.GenFds => GenFds.FdfParser
* GenFds.FdfParser => GenFds.Fd => GenFds.Fv => GenFds.GenFds =>

Gary Lin 89a69d4b64 BaseTools: Move FindExtendTool to GenFdsGlobalVariable.py
Importing "FindExtendTool" from GenFds.GenFds could create the following
circular imports:

* GenFds.FdfParser => GenFds.Capsule => GenFds.GenFds => GenFds.FdfParser

  GenFds.FfsFileStatement => GenFds.GuidSection => GenFds.GenFds =>

This commit moves "FindExtendTool" to GenFdsGlobalVariable.py to break
the circles. Besides, FindExtendTool is tweaked slightly with the
following changes:

ToolDefClassObject.ToolDefDict => ToolDefDict
TAB_GUID => DataType.TAB_GUID
TAB_TOD_DEFINES_TARGET => DataType.TAB_TOD_DEFINES_TARGET
TAB_TOD_DEFINES_TOOL_CHAIN_TAG => DataType.TAB_TOD_DEFINES_TOOL_CHAIN_TAG
