Allow overriding msix file name in MakerMSIX

[tgnhrkn]

Pre-flight checklist

• I have read the contribution documentation for this project.
• I agree to follow the code of conduct that this project uses.
• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Problem description

MakerMSIX always uses "appName.msix" as the output filename. appName is derived from packagerConfig.name (or package.json as a fallback). This doesn't allow for custom naming that includes (for example) version number which is useful for publishing.

Proposed solution

Add a configuration option like outputFileName to MakerMSIXConfig that overrides appName in outputPath in the make() function of MakerMSIX.

Alternatives considered

• Automatically adding the version number to the output file name. This is similar to what other makers (eg MakerDMG) do.
