Build System: Solve dependency problem for test

1. A test can add a runtime dependent test module by just setting
   LOCAL_REQUIRED_MODULES or LOCAL_TARGET_REQUIRED_MODULES. Then the dependent test
   module will be copied to testcase folder.
2. Do not install to $(TARGET_OUT_DATA) for testcase

BUG: 117224272

Test: 1. (a) vi cts/tests/tests/text/Android.mk
         (b) add LOCAL_REQUIRED_MODULES := CtsPrintTestCases
         (c) m -j CtsTextTestCases
         (d) Then, CtsPrintTestCases should also be built to testcase folder like below.
             ./target/product/generic_arm64/testcases/CtsPrintTestCases
