feat(ext/net): add signal option to Deno.connect() (#27113)

Ref #26819

An optional **timeout** parameter has been added to the
**Deno.connect()** interface. This parameter allows specifying a timeout
(in milliseconds) within which the application must establish a
connection. If the timeout is exceeded without successfully connecting,
the operation is automatically aborted with an error. If the parameter
is not provided, the default behavior remains unchanged (no timeout).
Currently, the timeout functionality is implemented only for TCP
connections. Other connection types are not affected by this change.
