Add `programmer` to the sketch profile

[dankeboy36]

Describe the request

Include programmer in the sketch project file (aka sketch.yaml).

Getting the debug information (via debug --info) requires the fqbn and the programmer.

The FQBN and all custom board options are "encoded" in the fqbn property of the profile, but there is no way to store the programmer. If the port, protocol, fqbn, etc., can have a default, maybe adding a slot for the programmer could also make sense.

Assume this profile:

profiles:
  nanorp:
    fqbn: arduino:mbed_nano:nanorp2040connect
    programmer: p1
    platforms:
      - platform: arduino:mbed_nano (2.1.0)

default_profile: nanorp

Running arduino-cli debug --info --profile nanorp would implicitly run arduino-cli debug --info --fqbn arduino:mbed_nano:nanorp2040connect --programmer p1.

Describe the current behavior

There is no way to store the programmer in the sketch profile. This will be a problem in Arduino IDE when people want to opt in and start storing the FQBN + the custom board options in a file and sharing it with others.
