ilspycmd crashing if no valid ICU package is found

[siegfriedpammer]

$ ilspycmd
Process terminated. Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

We should disable globalization support as described here: https://github.com/dotnet/runtime/blob/main/docs/design/features/globalization-invariant-mode.md#enabling-the-invariant-mode as it is not necessary for the decompiler to be localized.
