Roll chromium_revision 274825:280149 to fix GN

Due to http://crbug.com/389883 GN currently doesn't execute
unless the top folder is named 'src'.

To work around this, perform the following changes to a
checkout that currently has "trunk" as the root folder:
1. Rename trunk -> src
2. Remove .gclient_entries file (will be re-created)
3. Edit .gclient and:
  * set the name of the solution to "src"
  * add/change the custom_vars dict for the solution to
    have a key like this:
    "custom_vars" : {
      "root_dir" : "src",
    },
4. Run gclient sync

The buildbots already have this done and gets a "src"
dir for their checkouts.

I also workaround some recent changes for sanitizer tools
and add a copy of Chromium's tsan_suppressions.cc to prepare
for TSan v2 (since v1 that libyuv is currently using is
deprecated and should be removed).

BUG=libyuv:338
TEST=Currently working trybot passing + local compile on Linux in
Debug,Release and with ASan+TSan v2 using:
GYP_DEFINES="asan=1 release_extra_cflags=-g use_allocator=none" ./gyp_libyuv && ninja -C out/Release
GYP_DEFINES="tsan=1 release_extra_cflags=-g use_allocator=none" ./gyp_libyuv && ninja -C out/Release
