MSSQL: Throw validation error if "ordered" is specified in createSequence/alterSequence

[nvoxland]

Description

SqlServer does not support an ordered/unordered clause in sequences and so Liquibase should throw a validation error if the user attempts to specify it in either createSequence or alterSequence.

https://docs.microsoft.com/en-us/sql/t-sql/statements/create-sequence-transact-sql?view=sql-server-ver15

Fixes #2528

[nvoxland]

I did not add an automated test because the change simply adds to the configuration of CreateSequenceGenerator and AlterSequenceGenerator vs. adding new logic. I'm working on a better way to be able to capture the configuration details in tests but do not have that ready, and this one-off check seems unuseful.

NOTE: For users who have ordered=false in their changelog currently, it will be a breaking change because their changelogs will now fail validation.

That seems expected because they are telling us they want to say they can be unordered, and we can't give that to them and should tell them that. It seems unlikely that people will be many people will be setting ordered=false in sqlserver.

It won't be a problem for mssql users who had ordered=true in their changelog, because previously that would have thrown a SQL exception and now it throws a validation exception. So it's not breaking something that worked before, it just gives a better error.

Manual Testing
Setup
Use next changelog:

    	<changeSet id="1" author="Liquibase" labels="setup">
    		<createSequence sequenceName="SETUP_SEQUENCE" startValue="1" incrementBy="1"/>
  	</changeSet>

	<changeSet id="2" author="Liquibase" labels="create">
    		<createSequence sequenceName="TEST_SEQUENCE" startValue="1" incrementBy="1" ordered="true" />
  	</changeSet>

	<changeSet id="3" author="Liquibase" labels="alter">
    		<alterSequence sequenceName="SETUP_SEQUENCE" ordered="true" />
  	</changeSet>

Run liquibase update --changelog-file changelog.xml --labels setup against MSSQL database

Test Cases
Verify update shows correct error message for createSequence tag with ordered attribute

• liquibase --changelog-file changelog.xml --labels create
• ordered is not allowed on mssql error message is shown

Verify update shows correct error message for alterSequence tag with ordered attribute

• liquibase --changelog-file changelog.xml --labels alter
• ordered is not allowed on mssql error message is shown
