Android stack traces do not include file names and line numbers on CoreCLR

Description

On Android, stack traces do not include file names and line numbers on CoreCLR. This is a tracking issue to improve stack traces verbosity.

Added stack trace pattern matching

private static string FileInfoPattern(string fileLinePattern) =>
            PlatformDetection.IsAndroid ? "" : fileLinePattern;

in StackTraceTests.ToString_Async.
