Hello,

Please review this fix which removes some inefficiencies in calculating what needs to be built. All these fixes together result in about 20% faster execution time on Windows when running make when there is nothing to do.

Here is what was done:

* The java module dependency macro makes a shell call each time. Calculate dependencies once and put them in a makefile that can just be included. Moved this logic away from MakeBase since only a few makefiles need this. * LibCommon.gmk, which is included by each module Lib-*.gmk file is running a FillCacheFind over all native source. This was moved to a more specialized FillCacheFind for each module that actually needs it. Most don't. * GensrcProperties.gmk is running FillFindCache over all java source files. It's actually better to just skip the cache here since there are so few calls to CacheFind anyway. * GensrcLocaleDataMetaInfo.gmk is running a find over all java src in jdk, but the files it needs are either in java.base or jdk.localedata so the find could be limited and much faster.
