Reland "Export symbols needed by the Chromium component build (part 1)."

This reverts commit 16fe3f290a524a136f71660a114d0b03ef501f10.

Reason for revert:
After discussing this problem with nisse@ and yvesg@, we decided to modify
how RTC_EXPORT works and avoid to depend on the macro COMPONENT_BUILD.
RTC_EXPORT will instead depend on a macro WEBRTC_COMPONENT_BUILD (which
can be set as a GN argument which defaults to false).
When all the symbols needed by Chromium will be marked with RTC_EXPORT we
will flip the GN arg in Chromium, setting to to `component_build` and from
that moment, Chromium will depend on a WebRTC shared library when
`component_build=true`.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.

Authoritative list of directories that contain the native API header files.
