[11u]: RFR 8235686: Add more custom hooks in Bundles.gmk

[Langer, Christoph]

Hi,

please help to review this Oracle-11.0.7 parity backport for the build system.

Bug: https://bugs.openjdk.java.net/browse/JDK-8235686
Original Change: https://hg.openjdk.java.net/jdk/jdk14/rev/91a3f092682f
Webrev: http://cr.openjdk.java.net/~clanger/webrevs/8235686.11u/

The patch needed some trivial resolves and is preceded by JDK-8232572 which was already reviewed and will be pushed before this one.

Thanks
Christoph
