CoreCLR app size can be larger than with Mono

Large ReadyToRun images in simulator builds

Simulator builds do not strip native symbols by default. For large apps, native symbols in the ReadyToRun image can make simulator builds much larger and slower to deploy, even in Release builds.

Set NoSymbolStrip=false to strip these symbols and reduce app size, at the cost of having fewer symbols in simulator crash reports.
