feat: EXPOSED-487 Add ability to pass custom sequence to auto-increment column

[joc-a]

Description

Summary of the change:
Add ability to pass custom sequence to auto-increment column.

Detailed description:

• What:
  Added autoIncrement overload function that accepts a sequence of type org.jetbrains.exposed.sql.Sequence.
• Why:
  I noticed that it even though it was possible to create a custom sequence using SchemaUtils.createSequence(mySequence) and manually call mySequence.nextIntVal() or mySequence.nextLongVal() when inserting, it was not possible to simply pass it to an auto-increment column to use internally.
• How:
  A secondary constructor was added to AutoIncColumnType to pass it the custom sequence. A sequence field was also added to AutoIncColumnType and this field is now used instead of autoincSeq in SchemaUtils.kt where it was used to create/drop a sequence.
