We now provide AOT support to generate repository implementations during build-time for JDBC repository query methods.
Supported Features
Derived query methods, @Query and named query methods
* @Modifying methods returning void, int, and long
* Pagination, Slice, Stream, and Optional return types
* DTO and Interface Projections
* Value Expressions
Excluded methods
* CrudRepository, Querydsl, Query by Example, and other base interface methods as their implementation is provided by the base class respective fragments
* Methods whose implementation would be overly complex
* Methods accepting ScrollPosition (e.g. Keyset pagination)

Entities may be annotated with `@Id` and `@Embedded`, resulting in a composite id on the database side.
The full embedded entity is considered the id, and therefore the check for determining if an aggregate is considered a new aggregate requiring an insert or an existing one, asking for an update is based on that entity, not its elements.
Most use cases will require a custom `BeforeConvertCallback` to set the id for new aggregate.
For an entity with `@Embedded` id, the back reference used in tables for referenced entities consists of multiple columns, each named by a concatenation of <table-name> + `_` + <column-name>.
E.g. the back reference to a `Person` entity, with a composite id with the properties `firstName` and `lastName` will consist of the two columns `PERSON_FIRST_NAME` and `PERSON_LAST_NAME`.
This holds for directly referenced entities as well as `List`, `Set` and `Map`.

Deprecate original DialectResolver and JdbcArrayColumns as they've been in the wrong package and introduce replacements in the dialect package. Let deprecated types extend from their replacements to retain compatibility.
Make instance holders final, fix Javadoc typos, update reference docs.

Collection valued attributes now get ignored.
Before RelationalExampleMapper tried to generate predicates for these, resulting in invalid SQL.
Closes#1969
SpEL expressions in queries get processed in two steps:
1. First SpEL expressions outside parameters are detected and processed.
This is done with a `StandardEvaluationContext` with the variables `tableName` and `qualifiedTableName` added.
This step is introduced by this commit.
2. Parameters made up by SpEL expressions are processed as usual.
