BaseTools: Update Build tool to support multiple workspaces

WORKSPACE is still kept.
New PACKAGES_PATH is introduced to specify the additional WORKSPACEs.
In PACKAGES_PATH, ';' is separator in Windows, ':' is separator in Linux.

Build directory is in WORKSPACE. Package, BaseTools and Conf directory
will be found from WORKSPACE and PACKAGES_PATH.

In implementation, BaseTools adds MultipleWorkspace class for
the file path conversion from WORKSPACE and PACKAGES_PATH.

Verify two tree layouts.
Root\edk2\MdePkg
Root\edk2\MdeMdeModulePkg
Root\edk2\...
1. set WORKSPACE=Root\edk2
2. set WORKSPACE=Root, and set PACKAGES_PATH=Root\edk2
