BuildMetadataBin.cmd fails if the display language is not English

[krzysdz]

When looking for errors, if the Id is "CS0246" the diagnostic message is checked using a regular expression:

win32metadata/sources/ClangSharpSourceToWinmd/ClangSharpSourceCompilation.cs

Lines 150 to 163 in d32d7f4

	// Symbol not found. See if it's in the type import list
	if (diag.Id == "CS0246")
	{
	var symbolNameRegx = new System.Text.RegularExpressions.Regex(@"The type or namespace name '(\w+)'");
	var match = symbolNameRegx.Match(diag.GetMessage());
	if (match.Success)
	{
	var symbolName = match.Groups[1].Value;
	if (this.typeImports.ContainsKey(symbolName) || typeImports.ContainsKey($"{symbolName}(interface)"))
	{
	continue;
	}
	}
	}

The GetMessage function returns a localised message, so there is no match if language other than English is used and the command fails with multiple errors.

Hopefully, this problem should be easy to fix, because an IFormatProvider can be passed as an argument to use the appropriate language - see https://github.com/krzysdz/win32metadata/commit/5b142922ebe17c8e6587a33471b2e1892308789b:

                    var symbolNameRegx = new System.Text.RegularExpressions.Regex(@"The type or namespace name '(\w+)'");
                    var culture = new System.Globalization.CultureInfo("en-US");
                    var match = symbolNameRegx.Match(diag.GetMessage(culture));

Thanks @krzysdz for the advice on the fix!
