[DebugInfo] Enable call site debug info for ARM and AArch64

ARM and AArch64 SelectionDAG support for tacking parameter forwarding
register is implemented so we can allow clang invocations for those two
targets.
Beside that restrict debug entry value support to be emitted for
LimitedDebugInfo info and FullDebugInfo. Other types of debug info do
not have functions nor variables debug info.
