Allow configuring a custom JIT metrics path

[MatejKafka]

Problem Description

dnSpy stores JIT metrics in AppData/Local/dnSpy. I would like to use dnSpy as a portable app and redirect all config/data files to a custom directory. I can change the settings path using --settings-file, but there's no way to change the metrics path:

dnSpy/dnSpy/dnSpy/MainApp/BGJitUtils.cs

Line 33 in ca6a050

return Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), Constants.DnSpyFile, "Startup" + (IntPtr.Size * 8).ToString(), frameworkDir);

Proposal

Add a --profile-dir CLI argument to dnSpy.exe, which changes where the metrics and profiles are stored to the passed path.
