[Android] Make content_shell_apk and chromium_testshell components friendly.

This includes the remaining changes to atleast _compile_ the above
targets. More work is needed for starting up the apps and running.

Inclues:
- Misc EXPORT additions (I assume I can TBR these)
- Introduce a ShellDialogs JNI registrar since it's now a separate
  component and ui can't depend on it.
- Random gyp tweaks that are needed to fully specify dependencies
- Change from using NPN_MemAlloc to just plain malloc for the java
  bridge. For some reason the NPN_MemAlloc symbol cannot be found in the
  component build, but regardless all our implementations end up calling
  straight throught to malloc.
