[topgen] Support custom external name format
Current Inter-module signal has fixed naming rule for every inter-module
signals. It creates weird naming format for external ports. External
ports doesn't have `_o`, `_i` suffixes and also it always has the
instance name in front of the signal name such as `clkmgr_clk_main`.
This commit is to support custom top signal name for external type
(other type will be addressed in following PRs). To support it,
top_earlgrey.hjson format is slightly revised. Please see the
`inter_module`.`external` data field.
This is related to Issue #3095
