verilog bazel rules should emit System/VerilogInfo

[proppy]

It seems that currently dslx/ir_verilog rules are connected to bazel_rules_hdl's verilog_library thru brick and mortar files, see:

xls/xls/examples/BUILD

Lines 407 to 412 in 75930f7

	verilog_library(
	name = "find_index_5000ps_model_unit_verilog",
	srcs = [
	":find_index_5000ps_model_unit.v",
	],
	)

It'd be nice to leverage instead structured bazel types like VerilogInfo: https://github.com/hdl/bazel_rules_hdl/blob/main/verilog/providers.bzl#L19, it could also allow simulation rules to ask for specific variant of (system)verilog depending of their frontend capabilities.
