adi_v5_dapdirect: add support for adapter drivers that provide DAP API

Browse Source 
Some high level adapters, like STLINK-V3 and new firmware for
ST-Link/V2, provide API to directly access the DAP registers
hiding the details of the physical transport JTAG or SWD.
OpenOCD has already the intermediate API in struct dap_ops that
are suitable for such adapters, but are not exposed to the
adapter drivers.

Add in struct adapter_driver two independent struct dap_ops for
the cases of physical JTAG and SWD transport.
Add new transport names "dapdirect_jtag" and "dapdirect_swd", to
be used by the drivers that provide one or both DAP API.
Add the necessarily glue in target/adi_v5_dapdirect.c
