RFR: 8307160: Fix AWT/2D/A11Y to support the permissive- flag on the Microsoft Visual C compiler [v50]

[Julian Waters]

> We should set the -permissive- flag for the Microsoft Visual C compiler, as was requested by the now backed out [JDK-8241499](https://bugs.openjdk.org/browse/JDK-8241499). Doing so makes the Visual C compiler much less accepting of ill formed code, which will improve code quality on Windows in the future.
