SqlServerDialect should always quote identifiers

Description

Microsoft SQL Server has reserved keywords such as order that cannot be used as identifiers unless they are quoted

This works in spring-data 2.1.x. Unfortunately in #914 identifiers quoting was disabled by default for this dialect. That made it impossible to migrate from 2.1.x to 2.2+

When I declare an entity like this:

@Table
data class MyEntity(
    @Id
    val id: Long? = null,
    val order: Int,
)

then SQL Servers throws exceptions like this one: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'order'.

Solution proposal

I suggest create new IdentifierProcessing type QUOTED = create(Quoting.ANSI, LetterCasing.AS_IS) and use it in SqlServerDialect.

I ported it back to 2.4. It will be released with 2.4.7

I see that quoting was introduced in 3.0.0, in 2.4.x it doesn’t quote identifiers. Any chances it might be backported to 2.4.x?
