Update the `TestCompiler` so that classes can be defined using
a `Lookup`. This update allows package-private classes to be
accessed without needing a quite so unusual classloader setup.
The `@CompileWithTargetClassAccess` should be added to any
test that needs to use `Lookup` based defines. The test will
run with a completed forked classloader so not to pollute the
main classloader.
This commit also adds some useful additional APIs.

With a Java 8 baseline in place for quite some time now, it no longer
makes sense to refer to features such as annotations as "Java 5
annotations".
This commit also removes old `Tiger*Tests` classes, thereby avoiding
duplicate execution of various tests.
This commit improves the documentation for test execution events,
especially with regard to the fact that, by default, a
BeforeTestClassEvent is not published for the first test class using a
particular ApplicationContext.
This commit also introduces tests that verify the default behavior and
the ability to change the default behavior with a custom
TestExecutionListener that eagerly loads the context.

Prior to this commit, there was no way to configure type-safe rollback
rules for transactions.
Even though a rollback rule could be defined using a Class reference
via the `rollbackFor` and `noRollbackFor` attributes in @Transactional,
those Class references got converted to Strings (as the fully qualified
class names of the exception types) in RollbackRuleAttribute which then
applied a pattern-based matching algorithm as if the Class references
had been supplied as Strings/patterns to begin with, thereby losing the
type information.
Pattern-based rollback rules suffer from the following three categories
of unintentional matches.
- identically named exceptions in different packages when the pattern
does not include the package name -- for example,
example.client.WebException and example.server.WebException both
match against a "WebException" pattern.
- similarly named exceptions in the same package when a given exception
name starts with the name of another exception -- for example,
example.BusinessException and example.BusinessExceptionWithDetails
both match against an "example.BusinessException" pattern.
- nested exceptions when an exception type is declared in another
exception -- for example, example.BusinessException and
example.BusinessException$NestedException both match against an
"example.BusinessException" pattern.
This commit prevents the latter two categories of unintentional matches
for rollback rules defined using a Class reference by storing the
exceptionType in RollbackRuleAttribute and using that type in the
implementation of RollbackRuleAttribute.getDepth(Class, int), resulting
in type-safe rollback rules whenever the `rollbackFor` and
`noRollbackFor` attributes in `@Transactional` are used.
Note that the first category of unintentional matches never applied to
rollback rules created from a Class reference since the fully qualified
name of a Class reference always includes the package name.

This commit repackages the Javapoet library into spring-core so that it
can be used by the AOT engine without requiring a specific version.
Closes gh-27828
Prior to this commit, if AOP proxy generation was configured with
proxyTargetClass=true (which is the default behavior in recent versions
of Spring Boot), beans implemented as lambda expressions or method
references could not be proxied with CGLIB on Java 16 or higher without
specifying `--add-opens java.base/java.lang=ALL-UNNAMED`.
This commit addresses this shortcoming by ensuring that beans
implemented as lambda expressions or method references are always
proxied using a JDK dynamic proxy even if proxyTargetClass=true.
Closes gh-27971
