chromium: Update all channels to latest versions.

With this commit, the following new upstream versions are introduced:

stable: 35.0.1916.114 -> 35.0.1916.153
beta:   35.0.1916.86  -> 36.0.1985.67
dev:    36.0.1964.2   -> 37.0.2054.3

All builds successfully tested on my machine, however in order to update
the beta and dev channels, a few additional modifications were
necessary:

 * Update/rebase USER_NS sandbox patch for version 36 and higher.
 * Create address_input_strings.grdp before running gyp in version 37.
 * Remove an empty string leftover from 0517041a.
 * Add patch for building bundled Angle for version 37.

The patch for Angle is to remove reliance on git being present during
build and is from https://chromium-review.googlesource.com/202048

 but
with own modifications to remove/fix Windows-specific parts within the
patch file.
