Refactor handling of logging and user messaging.

[noppej]

probe-rs recently adopted the tracing crate for logging. This opened up the possibility to cleanup how logging was implemented in the VSCode extension and associated probe-rs-debugger.

This PR will do the following:

• As a maintenance task, update the extension dependencies, and bump the version number.
• Add a launch.json setting to direct probe-rs logging to a JSON file, which can later be analyzed with the log viewer.
• Remove any probe-rs (RUST_LOG) logging from the data being reported in the VSCode debug console. It is currently interspersed with debug adapter logging, and although somewhat informative, it makes it less than useful when analyzing probe-rs specific issues.
• Refactor the VSCode extension and probe-rs-debugger handling of MS DAP events and messages, to be more useful (objective opinion) to users of the extension.
• probe-rs-debugger logging will happen according to these rules:
  1. If the RUST_LOG environment variable is set, use it as a LevelFilter to configure a subscriber that logs to a file in the system's application data directory.
  2. Irrespective of theRUST_LOG environment variable, configure a subscriber that will write with LevelFilter::ERROR to stderr (because these errors are picked up and reported to the user by the VSCode extension).

NOTE This release requires changes to the launch.json files in user projects

• The consoleLog property only supports one of three values [Console, Info, Debug]
• The extension will now honour env properties, for example:

  "env": {
      "RUST_LOG": "warn",
      "DEFMT_LOG": "debug"
  }
  

For testing, feel free to use the extension binary

I added a few nits that are not a must but would be nice :)

Much appreciated ... nits or not, they help improve code quality, and worth the few minutes it takes to address. Thanks !
