targets: Add sample target for controller on Dialog CMAC

This adds sample target for building NimBLE controller (blehci app)
for Dialog CMAC. It is used by default when "dialog_cmac" transport
is selected on host side.

Sample target should be used as a base for creating customized targets.
The default settings for timigs are recommended values and should not
be changed unless required.
