Parsing Error in Coco Plugin

Issue Description

When configuring coverage scanner options in project settings, the plugin generates invalid CMake code that causes build failures.

Environment

QtMCUs 2.9.1

Steps to Reproduce

Create or open an MCU project in Qt Creator 16
Navigate to project settings
Configure coverage scanner options with Windows-style paths, for example:

--cs-on --cs-mcdc --cs-mcc --cs-exclude-file-abs-wildcard=C:\Qt* --cs-include-path=C:\Qt\QtMCUs\2.9.1\demos\thermo

Click "Save & Re-configure"

We get the following errors:

[cmake] loading initial cache file C:\Qt\QtMCUs\2.9.1\demos\thermo\cocoplugin.cmake
[cmake] CMake Warning (dev) at cocoplugin.cmake:3 (set):

[cmake] CMake Error at cocoplugin.cmake:46 (find_program):
[cmake]   Could not find code_coverage_c_compiler using the following names:

[cmake]

[cmake] – Configuring incomplete, errors occurred!

The error related to finding the code coverage compiler (csarm-none-eabi-gcc.exe) needs investigation, as it persists even after fixing the path escaping problems.

Workarounds

Manually changing backslashes to forward slashes in the coverage scanner options resolves the escaping issue, but the plugin should handle this conversion automatically.
