Tim van der Lippe 28af9fbe78 Reland "Do not overwrite generated files when contents remains the same"
This reverts commit aaae6b021a.

Reason for revert: always check if tsconfig.json needs to be updated

Original change's description:
> Revert "Do not overwrite generated files when contents remains the same"

> This reverts commit c1e414725a.

> Reason for revert: Seems to be the cause for CQ compilation errors:

> Original change's description:

> > To ensure that build timestamps don't unnecessarily cause full rebuilds,

> > On a new year, the file contents would actually be different, so it

> > timestamp changes, it won't cause is unnecessarily to rebuild all these
