Revert of Use visual studio toolchain from depot_tools for PDFium compilation (patchset #3 id:40001 of https://codereview.chromium.org/1897523002/ )

Reason for revert:
Clang build is broken. drm build has some problem. Will revert this change for now.

Original issue's description:
> Use visual studio toolchain from depot_tools for PDFium compilation
>
> Change to use visual studio toolchain from depot_tools by default.
> Setting DEPOT_TOOLS_WIN_TOOLCHAIN=0 allows compilation using system
> toolchain as before.
>
> Using toolchain from depot_tools unifies the compilation
> environment, and brings the benefits of automated update, bug fixes
> etc.
>
> Committed: https://pdfium.googlesource.com/pdfium/+/590f2d9e057a0d5b17a9706affd3c6115265021b
