Send configuration fo mesonbuild to language server, if it changed

[JCWasmx86]

Configuration format is like this in your .settings.json

{
    "mesonbuild.Swift-MesonLSP": {
        "others": {
            "ignoreDiagnosticsFromSubprojects": true,
        },
        "linting": {
            "disableNameLinting": true,
            "disableCompilerIdLinting": true,
        }
    }
}

Testing:

• Remove downloaded language server from the vscode extension
• Use binaries from HEAD of https://github.com/JCWasmx86/Swift-MesonLSP and drop them in PATH
• Use e.g. https://github.com/hse-project/hse

Your diagnostics will look like this:

Merge the config listed above with your .settings.json.

Only this error will be left:

(A bug on my side, as my heuristics will never be able to guess the sophisticated subdir calculation for hse-python, but that's offtopic here)

Only thing missing here is the auto-completion/diagnostics in the settings.json file.

Not sure, if we need a changelog item for that, as it is only a little user-visible.

Let's just add a changelog entry.

It is funny that you are testing with HSE. Fun project to work on. Too bad Micron laid us all off :(

[JCWasmx86]

Not sure how useful the changelog item is. I would quickly write a doc for that on my git repo with all the options. That's the best way I can keep it in sync I think

[tristan957]

That is fine with me.
