Add `DynamicInstrumentationManagerService` 

Adds a new service with a single operation
`getExecutableMethodFileOffsets`. The operation allows the caller to
fetch information about the native executable of a given method. The
operation's access control is limited to the UprobeStats module.

Given a method in the form of fully qualified class name, method
name, and fully qualified parameter list, the operation returns
information from the ODEX file associated with that method. If the
method isn't precompiled, the operation returns null.
However, ART can be enhanced to support returning information about
JIT compiled methods in the future.

Test: DynamicInstrumentationManagerServiceTests, ExecutableMethodFileOffsetsTest
