Refactor Call-based tests.

Greatly reduces duplication of constants and setup code for tests based
on the new webrtc::Call APIs. It also makes it significantly easier to
convert sender-only to end-to-end tests as they share more code.

TSan: Move suppressions to source file.

Chromium has deprecated text-file based suppressions for
TSan (v2) and is about to remove the support for it in the
test toolchain in https://codereview.chromium.org/357673002/

This CL moves our suppressions to a source file (based on the
Chromium copy).
It also moves the sanitizer_options.gyp into webrtc/build.

BUG=chromium:302040
TEST=Locally executing all the standalone tests under TSan v2.
