8251861: Remove unused jdk.internal.ref.SoftCleanable and WeakCleanable

[kiranoracle]

Hi Guys,

Please review the fix to remove jdk.internal.ref.SoftCleanable and WeakCleanable classes as there is no visible usage of them in JDK. Currently, only PhantomCleanable is used.

More information can be viewed at https://mail.openjdk.java.net/pipermail/core-libs-dev/2020-August/067997.html

Bug: https://bugs.openjdk.java.net/browse/JDK-8251861

Thanks,
Kiran
