itm: rework itm commands before 'init'

If the command 'itm port[s]' is issued before 'init', the ITM can
not be programmed because OpenOCD cannot access the target yet.
The configuration is recorded and applied after target examine.
The current test to trigger the ITM delayed-programming is based
on the TPIU configuration. This is allowed because the only use of
ITM it so send data through TPIU.
In case of system TPIU, not belonging anymore to the target, there
is no more association between target ITM and system TPIU.

Add a flag to record the pending ITM configuration requested
before 'init' and test the flag to trigger the delayed-programming
of the ITM.
