[HostStubGen] Support replacing constructor calls to methods 

There are some cases where we need to modify constructors of classes
in the JDK. Update the existing method call replacement mechanism to
support also support constructors.

Test: atest hoststubgen-test-tiny-test
Bug: 397498134
Flag: EXEMPT host side change only
