stlink: support of ST-LINK TCP server using stlink-dap and hla

Browse Source 
Quote: The ST-LINK TCP server is an application to share the debug
interface of a single ST-LINK board among several host applications,
typically a debugging tool and a monitoring tool.

Note: ST-Link TCP server does not support the SWIM transport.

ST-LINK TCP server allows several applications to connect to the same
ST-Link through sockets (TCP).

To use ST-LINK TCP server:
 - using stlink-dap : use 'st-link backend tcp [port]'
 - using hla : use 'hla_stlink_backend tcp [port]'

the default port value is 7184
