Merge 'Simulator: ALTER TABLE' from Pedro Muniz
...
Adds `ALTER TABLE` to the simulator. Currently, there are no properties
that generate `ALTER TABLE`. The query is only generated in
`Property::Query` or in extension queries.
Conditions to generate `ALTER TABLE`:
- In differential testing, do not generate `ALTER COLUMN` as SQLite does
not support it.
- If there is only 1 column, or all columns are present in indexes, do
not generate a `DROP COLUMN` as it would be an error in the database
- if there are no tables, obviously do not generate `ALTER TABLE`
Some fixes:
- handle NULL generation in `GTValue` and `LTValue`, as we now have to
handle nulls due to `ADD COLUMN` adding cols with NULL
- correctly compare NULLs in `binary_compare`
Closes #3650

Write-write conflict is not an error that stops the simulation. Note
that the transaction is rolled back automatically.
