[runtime] Use no-op for SufficientExecutionStack on Linux (#5543)

We had previously responded to bad performance on android by stubbing out
ves_icall_System_Runtime_CompilerServices_RuntimeHelpers_SufficientExecutionStack
on android. This was necessary because the call to pthread_attr_getstack ()
will read /proc/self/maps. When used inside of a hot function, the performance is terrible.

Fixes https://bugzilla.xamarin.com/show_bug.cgi?id=58911
