Fix build and initial Chrome runtime issues on macOS (see issue #2969)

This change moves shared resource initialization to a common location and
disables crash reporting initialization in chrome/ code via patch files.

When using the Chrome runtime on macOS the Chrome application window will
display, but web content is currently blank and the application does not
exit cleanly. This will need to be debugged further in the future.
