RFR: 8317510: Change Windows debug symbol files naming to avoid loosing info when an executable and a library share the same name

[Frederic Thevenet]

When building OpenJDK on Windows using "--with-native-debug-info=external", the resulting debug symbols are saved in files located in the same folder as the corresponding executable or library and named by swapping the extension ".exe" or ".dll" for a ".pdb" one (or "diz" if option "--with-native-debug-info=zipped" is used), which means that in the event of an exe and a dll file sharing the same target folder and file name (e.g. `bin\java.exe` and `bin\java.dll`), we have to choose whether symbols in `bin\java.pdb` will refer to the exe or the dll; we can't have both.

This PR addresses this issue by adopting a different naming strategy for the resulting symbol files where we keep the full name of every file - including its `dll` or `exe` extension) and then add the appropriate `.pdb`, `.map` or `.diz` extension .

For instance,  `jvm.dll` symbols are no longer called `jvm.pdb` but instead `jvm.dll.pdb`. Similarly, it is now `jvm.dll.diz` when using zipped symbols, and "jvm.dll.stripped.pdb" for stripped symbols (i.e. when "--with-external-symbols-in-bundles=public" is used).

The PR also removes the existing filtering for java.pdb, jimage.pdb and jpackage.pdb used to guaranty the dll symbols were bundled over the ones from the exe, since we no longer need that.
