[eclipse-pmc] Request PMC approval to remove method not used anymore

[Szymon Brandys <Szymon.Brandys@xxxxxxxxxx>]

GOALS/BENEFITS:

org.eclipse.core.filesystem.IFileInfoFilter was introduced at the beginning
of Resource Filter API work.
Later it was left on purpose despite it is not referenced by any
core.filesystem or core.resources facility.
The idea was that this could be a common interface for FileInfo filters,
however since we don't have consumers of this API,
we should not introduce this API in 3.6.

I wanted to remove the code during the M6 milestone week,
but have held it till now to avoid problems with M6 candidate builds.

There are no users/references of it inside the SDK.

ASSOCIATED BUGS:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=305653

RISKS:
None since it is not used.

PERFORMANCE IMPACT:
None.

Let me know if you have any questions.
