[vcpkg] CMAKE_SYSTEM_PROCESSOR is missing if VCPKG_TARGET_ARCHITECTURE is arm or arm64. (#13465)
This change tries to fix issue #13395.

Root cause:
In script mode, cmake won't populate CMAKE_SYSTEM_PROCESSOR parameter automatically. That parameter is
required by libpng to configure build parameters. To fix this issue, we need explicitly set CMAKE_SYSTEM_PROCESSOR
value.

Verify:
On arm64-linux host, run `./vcpkg install tesseract:arm64-linux`.
