prog: repair arrays/buffers with incorrect size in Deserialize

For string[N] we successfully deserialize a string of any length.
Similarly for a fixed-size array[T, N] we successfully deserialize
an array of any size.
Such programs later crash in foreachSubargOffset because static size
Type.Size() does not match what we've calculated iterating over fields.
The crash happens only in SerializeForExec in syz-fuzzer,
which is especially bad.
Fix this from both sides:
1. Validate sizes of arrays/buffers in Validate.
2. Repair incorrect sizes in Deserialize.
