This change fixes the buffer size calculation for `STRUCT`s nested inside `LIST`s and for `MAP`s. It also fixes the validity mask size calculation for these cases. Testing: additional tests added with longer `MAP`s (to check nested `STRUCT`s) and with `NULL` values (to check validity masks). Fix: duckdb#437
