RFR: 8284016: Normalize handshake closure names

[Anton Artemov]

Hi, please consider the following changes:

There are many classes inherited from the `HandshakeClosure` class, but they do not follow the same naming convention. In this PR we address this issue, all names are normalized in the following way:

`XXXDummyClassNameClosure -> XXXDummyClassNameHandshakeClosure`

or

`XXXDummyClassNameHandshake -> XXXDummyClassNameHandshakeClosure`

or

`XXXStrangeClassName -> SomewhatSimilarNameHandshakeClosure`

Tested in GHA and tiers 1 - 3.
