Change debug info default variable tracking system.

Varible Scope info is being disabled. Variable
Live Range is being enabled. Debug info generated
for debug code is the same, changes only impact on
optimized code.

Variable Live Range updates variable's location
each time something happens to variable's
liveness. For more information see
https://github.com/dotnet/runtime/blob/master/docs/design/features/variabletracking.md
