Revert of 🎊 Have build_config targets depend only on other build_config targets

Revert of 🎊 Have build_config targets depend only on other build_config targets (patchset #3 id:40001 of https://codereview.chromium.org/2095913003/ )

Reason for revert:
Sheriff: reverting on suspicion of breaking the android build.

It looks like the apk packaging step fails when a required component is not found. This change looked like a likely culprit since it changes the naming conventions, and the problem was file not found.

Original issue's description:
> Have build_config targets depend only on other build_config targets
>
> This works by having android target names follow a naming convention.
> If a target name matches, then it is assumed to have a .build_config file.
> gn gen will raise an error if it doesn't. Likewise, if a target name
> does not match the filters, but does create a .build_config file, gn gen
> will fail on an assert.
>
> This change adds a bunch of naming-convention exceptions, which will
> be addressed in subsequent commits.
>
> Finally, why make this change? This allows all .build_config targets to be
> generated in just a few seconds, which will allow fast generation of
> build.gradle files for Android Studio integration.
