Update to version 77

Continuation of https://github.com/Eloston/ungoogled-chromium/issues/619 and https://github.com/Eloston/ungoogled-chromium/issues/675.

I have updated build.py and package.py for the new system (post-fragmentation refactor). The rest of the work should be updating GN flags and patches.

For those who want the latest version of Ungoogled Chromium for Windows (and not version 67), just click here.

With this, the chaos should be over. At least for a while.

After having replaced the foul #includes, this shows up:

../../chrome/browser/conflicts/module_info_binary_feature_extractor.cc(13,10):  fatal error: 'components/safe_browsing/proto/csd.pb.h' file not found
#include "components/safe_browsing/proto/csd.pb.h"
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There exists a csd.proto file in that folder, it’s just that it hasn’t been generated. Any help with the issue of proto generation would be appreciated, as I’ve never touched the subsystem.

Adding

public_deps = [
  "//components/safe_browsing:csd_proto",
]

to chrome\browser\conflicts\BUILD.gn seems to have fixed the issue. Currently compiling.
