Update chip-tool commands to use subscribe instead of report

[dhrishi]

Problem

Currently, examples/chip-tool uses report command to subscribe to attributes and report-event command to subscribe to events. The names are quite confusing as it is the subscribe interaction that is initiated and it will be the other end that reports the data (attribute/event)

Change overview

• Change the below commands:
  report -> subscribe
report-event -> subscribe-event
• Update generated code

Testing

• Tested manual compilation of chip-tool
• Verified that the changes are reflected in the help command:

$ ./out/debug/chip-tool switch
[1643113920.446514][379270:379270] CHIP:TOO: Missing command name
Usage:
  ./out/debug/chip-tool switch command_name [param1 param2 ...]
