[VSC-1568] get supported qemu targets from tools json

[brianignacio5]

Description

Use $IDF_PATH/tools/tools.json to obtain QEMU forks supported targets. From now any IDF_TARGET is mapped to them and fallback to esp32 and esp32c3 forks.

Fixes #1404

Type of change

• New feature (non-breaking change which adds functionality)

Steps to test this pull request

Provide a list of steps to test changes in this PR and required output

1. Click on "[QEMU Server]" on the status bar and run either QEMU Debug or Monitor. It should select the new esp32s3 (when available in ESP-IDF tools.json) target.
2. Execute action.
3. Observe results.

• Expected output:

How has this been tested?

Manual testing running any QEMU command (Debug, Monitor) to make sure IDF_TARGET is used to get the QEMU fork to use (xtensa or risc-v)

Test Configuration:

• ESP-IDF Version: 5.4
• OS (Windows,Linux and macOS): macOS

I confirmed that with this update the QEMU monitor allows using ESP32, ESP32C3 and ESP32S3. For some reason monitor only worked for ESP32, it does not seem to be a block on the extension but rather something on IDF or docker.

[Fabricio-ESP]

Checked using Windows and Mac connected to docker container.
The QEMU emulation is failing for esp32c3, and esp32s3 is missing form the json file, but manually adding the target allows the extension to send the command to QEMU.
The issue is related to ESP-EDF, no side effected detected on the VSCOde extension.

I've tested with ESP32C3 and QEMU monitor worked.
