Put dependency in apex_manifest.json
To generate ld.config.txt dynamically(b/123722631), each APEX should
provide some dependency information:
a) list of libraries which other APEXes(or system) can use from this apex
b) list of libraries which this apex uses from other APEXes(or system)
This change puts dependency information in apex_manifest.json at
build-time with two additional keys:
a) provideNativeLibs
b) requireNativeLibs
Bug: 138695532
Test: m (runs soong tests)
Test: find $OUT/apex -name apex_manifest.json -exec cat {} \;
(shows contents of apex_manifest.json files)
