Add an annotation processor that generates properties files for certain
auto-configuration class annotations. Currently attribute values from
@AutoConfigureOrder, @AutoConfigureBefore, @AutoConfigureAfter and
@ConditionalOnClass annotations are stored.
The properties file will allow optimizations to be added in the
`spring-boot-autoconfigure` project. Primarily by removing the need
to ASM parse as many `.class` files.

Previously, the algorithm that computes the String representation of a
class reference and a property type was shared. This lead to generic
information for group's `type` and `sourceType` property.
This commit separates that logic in two: `getQualifiedName` is now
responsible to generate a fully qualified class name while the existing
`getType` is solely responsible to generate a type representation for the
property. Only the latter has generic information.

This commit makes sure that a meta-data group exposed via a deprecated
`@Bean` method is deprecated as well. This also works if the class
in which the bean method is defined is itself deprecated.

Previously, if a property name had successive capital letters, the
generated meta-data would clean it in such a way it is defined as a
regular word. For instance a `myFOO` property would be written as
`my-foo` in the meta-data.
It turns out this decision is wrong as the binder has no way to compute
back the name of the property and therefore `my-foo` wouldn't bind to
`setMyFOO` as it should.
This commit updates the meta-data name generation algorithm to properly
identify such cases: `myFOO` now translates to `my-f-o-o`. While the
generated name is a bit ugly, it now provides a consistent binding
experience.

This commit detects case where the same set of keys are exposed several
times and prevents the compilation to complete. Previously, duplicate
keys were silently added to the meta-data.
Closes gh-5939
Previously, if a void method with a single argument was named "set", the
annotation processor wrongly considered it was a setter candidate. This
commit updates the condition to ignore it.
Closes gh-5826
Previously, the meta-data annotation processor was taking the first
setter that match the property name it has to handle. Contrary to
getters that are enforced by a return type (no argument), multiple
setter candidates may exist.
If a property's type got narrowed over time, the original setter may
have been marked as Deprecated. As the annotation processor takes the
first setter that matches based on the name only, it may pick up the
deprecated one and therefore mark the property as being (wrongly)
deprecatede in the meta-data.
It turns out that checking for the actual type of the setter parameter
brought a side effect: some primitive properties may use the primitive
or the Wrapper counter part. This commit not only look at the proper
setter based on the type but also fallback on the wrapper (or) primitive
if necessary.
