Add Jacoco support

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
