Investigate use of /permissive- on msvc

[Sqeaky]

On msvc /permissive- disables non-standard permissive behaviours. This could help avoid corner cases where the build breaks. This is default in newer version and the docs can be found here: https://docs.microsoft.com/en-us/cpp/build/reference/permissive-standards-conformance?view=vs-2019

This should be tested in the Jagati and if it doesn't break other packages it should be used by default. If it breaks everything horribly it should be documented here and dropped. If it needs some work it should be discussed.
