Modified fastdeploy dependencies to ensure that fast deploy is build as part of 'sdk' target

deploypatchgenerator is now a dependency of adb
deployagent is now a java_binary target and uses the built in 'wrapper' parameter to bundle deployagent.sh
fastdeploy.cpp code in adb modified to reference deployagent rather than deployagent.sh (required to work with built in wrapper functionality).
removed near-redundant fastdeploy_init and TFastDeployConfig singleton as per:
https://android-review.googlesource.com/c/platform/system/core/+/740521/12/adb/client/fastdeploy.cpp#36
relocated kFastDeployMinApi to more appropriate location

Test: rm -rf $ANDROID_ROOT/out
Test: make sdk -j40

Test: find out/ -iname deploypatchgenerator
Test: observe that deploypatchgenerator.jar has been built as a dependency of the sdk target

Test: mm
Test: adb install -r -f --force-agent --local-agent ~/example_apks/example.apk
Test: adb install -r -f --no-streaming --force-agent --local-agent ~/example_apks/example.apk
