Add support for instrumenting jars with jacoco. Unlike in Make, Jacoco in Soong is done entirely using jars. Instrumentation is enabled by EMMA_INSTRUMENT=true, and affects all apps. If EMMA_INSTRUMENT_FRAMEWORK=true then it also affects any java libraries listed in InstrumentFrameworkModules. Bug: 69629238 Test: m EMMA_INSTRUMENT=true EMMA_INSTRUMENT_FRAMEWORK=true SKIP_BOOT_JARS_CHECK=true WITH_DEXPREOPT=false Change-Id: If699715b277529cd7322ffca67c23b0746e1cccd
