'@' in compilerArgs doesn't work on Linux/Mac with 1.10.5 (Intellisense breaks)

### Environment

- OS and version: Ubuntu 20.04.4 LTS
- VS Code: 1.68.0
- C/C++ extension: 1.10.5
- OS and version of remote machine (if applicable): -/-
- GDB / LLDB version: not applicable.


### Bug Summary and Steps to Reproduce

Bug Summary:

When using PlatformIO with a Raspberry Pi Pico + Arduino project on Unix-like operating systems (Linux + Mac), Intellisense fails to find all include paths. Reverting the C/C++ by Microsoft extension to 1.9.8 solves the problem. The current version 1.10.5 that you have released 3 days ago breaks it.

Steps to reproduce:
1. Install the PlatformIO extension
2. Create a new project, choose "Raspberry Pi Pico" as board and "Arduino" framework
3. Let the default `src/main.cpp` code be.
4. Use the [project task](https://docs.platformio.org/en/latest/integration/ide/vscode.html#project-tasks) "Build", should be successfull
5. Observe intellisense error on `#include <Arduino.h>` line


### Debugger Configurations

Not relevant for Intellisense. Only `launch.json` is auto-generated by PlatformIO with 
```json
// AUTOMATICALLY GENERATED FILE. PLEASE DO NOT MODIFY IT MANUALLY
//
// PIO Unified Debugger
//
// Documentation: https://docs.platformio.org/page/plus/debugging.html
// Configuration: https://docs.platformio.org/page/projectconf/section_env_debug.html

Intellisense can be made to work with the latest extension when transforming the 
```
                "-iprefix/home/max/.platformio/packages/framework-arduino-mbed/cores/arduino",
                "@/home/max/.platformio/packages/framework-arduino-mbed/variants/RASPBERRY_PI_PICO/includes.txt",
```
part into seperate entries in the `path` array.

My guess: Recent versions don't parse `-iprefix <path> @<include file>` correctly. 

Include files come from https://github.com/arduino/ArduinoCore-mbed, includes.txt from https://github.com/arduino/ArduinoCore-mbed/blob/master/variants/RASPBERRY_PI_PICO/includes.txt.
