I fixed the problem and changed the documentation for UDTs.

[~iamaleksey] could you double check the changes?

> Currently, we allow altering of types. However, because we no longer store the length
for all types anymore, switching from a fixed-width to variable-width type causes issues.
commitlog playback breaking startup, queries currently in flight getting back bad results,
and special casing required to handle the changes. In addition, this would solve CASSANDRA-10309,
as there is no possibility of the types changing while an SSTableReader is open.
> For fixed-length, compatible types, the alter also doesn't add much over a cast, so users
could use that in order to retrieve the altered type.
