psoc6: Run flash algorithm asynchronously to improve performance

Existing psoc6 driver starts flash algorithm for each Flash row. This is
suboptimal from performance point of view, starting/stopping flash
algorithm for each row adds significant overhead. This change starts
flash algorithm and leaves it running asynchronously while driver
performs flash operations.

Performance gain is 170...250% depending on probe:

target: restructure dap support

- add 'dap create' command to create dap instances
- move all dap subcmmand into the dap instance commands
- keep 'dap info' for convenience
- change all armv7 and armv8 targets to take a dap
  instance instead of a jtag chain position
- restructure tap/dap/target relations, jtag tap no
  longer references the dap, daps are now independently
  created and initialized.
- clean up swd connect
- re-initialize DAP also on JTAG errors (e.g. after reset,
  power cycle)
- update documentation
- update target files
