Add VS2019 Support on ToolSetup Batches

Add VS2019 Support on ToolSetup Batches

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2182

Inorder to support VS2019, we add VS2019 config process
in Setup Batch Files,
Because VS2019 and VS2017 could using same vswhere.exe
to detect the InstallationPath,
So we add the -version as the parameter of vswhere
to get the correct VS2017/VS2019's InstallationPath

v3: In BaseTools\set_vsprefix_envs.bat,
    move WINSDK10_PREFIX setting into VCToolsInstallDir check condition.
