Add Database.Cursor methods to TIA

[benjaminloerincz]

Add these methods of namespace Database, class Cursor to TIA:

• Database.Cursor.fetch(Integer position, Integer count)
• Database.Cursor.getNumRecords()

[benjaminloerincz]

Both methods are not static as described in documentation. We need to inform the Salesforce documentation team to correct this. Errors on deployment:

• Non static method cannot be referenced from a static context: List Database.Cursor.fetch(Integer, Integer)
• Non static method cannot be referenced from a static context: Integer Database.Cursor.getNumRecords()
