RFR: JDK-8213187 Handle libwindowsaccessbridge need to access MSVCRT functions

[Magnus Ihse Bursie]

 From the bug report:

As a follow-up to JDK-8210944, find the best way to handle the needs of 
libwindowsaccessbridge to access the MSVCRT functions. Options include 
reverting JDK-8210944, and copying the MSVCRT*.DLL when needed, and/or 
possible other solutions.

I chose to revert JDK-8210944. I originally did JDK-8210944 to be able 
to finish a larger patch that moved all "CFLAGS := $(CFLAGS_JDKLIB)" 
constructs into SetupJdkLibrary, and then the filter-out logic 
completely screwed that up. But this patch has been lingering and 
bit-rotting while I've spent my time elsewhere, and it will not make it 
into JDK 12. I'll have to reconsider how I do that patch (possibly 
forcing that patch to include not only moving CFLAGS_JDKLIB into 
SetupJdkLibrary, but splitting up CFLAGS_JDKLIB in parts as well.

However, without this revert, we'll see a regression in JDK 12 on the 
loading of accessability libraries on Windows.
