make.bat: support existing toolchain paths with spaces

Previously if the default go toolchain (from "where go") contained spaces, then running make.bat would fail.

Fixes it to correctly treat paths with spaces. This is especially useful given that the default Go install path is under "C:\Program Files".

Fixes #57918
