[GOLD] Output_data_got create entry method addends

This patch makes all the Output_data_got methods that create new
entries accept an optional addend.

	PR 28192
	* output.h (Output_data_got::add_global): Add optional addend
	parameter.  Update comment.  Delete overload without addend.
	(Output_data_got::add_global_plt): Likewise.
	(Output_data_got::add_global_tls): Likewise.
	(Output_data_got::add_global_with_rel): Likewise.
	(Output_data_got::add_global_pair_with_rel): Likewise.
	(Output_data_got::add_local_plt): Likewise.
	(Output_data_got::add_local_tls): Likewise.
	(Output_data_got::add_local_tls_pair): Likewise.
	(Output_data_got::reserve_local): Likewise.
	(Output_data_got::reserve_global): Likewise.
	(Output_data_got::Got_entry): Include addend in global sym
	constructor.  Delete local sym constructor without addend.
	* output.cc (Output_data_got::add_global): Add addend param,
	pass to got handling methods.
	(Output_data_got::add_global_plt): Likewise.
	(Output_data_got::add_global_with_rel): Likewise.
	(Output_data_got::add_global_pair_with_rel): Likewise.
	(Output_data_got::add_local_plt): Likewise.
	(Output_data_got::add_local_tls_pair): Likewise.
	(Output_data_got::reserve_local): Likewise.
	(Output_data_got::reserve_global): Likewise.
