fix(parse): update tests and suites lists parsing

[Diogo21Costa]

This PR addresses a minor issue related to parsing the list of tests and suites in the config.dts files. Previously, there was a bug where parsing multiple suites and/or tests was not functioning correctly. For example, consider the following config.dts file:

/dts-v1/;
/ {
    platform = "qemu-aarch64-virt";
    log_echo = <1>;

    test_config {
        recipe_test {
            nix_file = "default.nix";
            suites = "SUCCESS_SUITE FAIL_SUITE";
            tests = "";
            log_level = "0";
        };
    };
};

Running the Nix build system with the command:

nix-build default.nix --argstr platform qemu-aarch64-virt --argstr list_suites "SUCCESS_SUITE FAIL_SUITE"

would result in the following error:

make: *** No rule to make target 'FAIL_SUITE'.  Stop.

With the changes introduced in this pull request, the corrected build command now looks like:

nix-build default.nix --argstr platform qemu-aarch64-virt --argstr list_suites "SUCCESS_SUITE\ FAIL_SUITE"

Please review and provide any comments or suggestions.

If I'm not mistaken, someone suggested to have multiple strings instead of a single string with all suite.
E.g.: suites: "SUCCESS_SUITE", "FAIL_SUITE";

@miguelafsilva5 you're right. In fact, in #22 the changes suppress this PR by implementing those changes. Maybe we should close this PR and proceed with the other one, right?

I don't think so. Ideally, both PR implement distinct features. It seems that #22 intends to be a PR dealing with the log and echo levels while this one aims to deal with parsing the suites and tests. No need to add unrelated features to other PRs when it can be done in the proper one.

Closed this PR as this changes are already in #22. And they the dts files will be removed from the current framework.
