Break tokens before checking if they are 'probably equal' 
Fixes #68489

When checking two `TokenStreams` to see if they are 'probably equal',
we ignore the `IsJoint` information associated with each `TokenTree`.
However, the `IsJoint` information determines whether adjacent tokens
will be 'glued' (if possible) when construction the `TokenStream` - e.g.
`[Gt Gt]` can be 'glued' to `BinOp(Shr)`.

Since we are ignoring the `IsJoint` information, 'glued' and 'unglued'
tokens are equivalent for determining if two `TokenStreams` are
'probably equal'. Therefore, we need to 'unglue' all tokens in the
stream to avoid false negatives (which cause us to throw out the cached
tokens, losing span information).
