This commit adds a check to the support code for the Gradle plugin
bootBuildImage task to ensure that the jar file that will be passed
to a builder is readable and has a valid directory. This prevents a
situation where the jar file cannot be read because it is prepended
with a launch script, and the builder does not receive any files to
process.

Notes have also been added to the Gradle plugin documentation to warn
against using a bootJar launchScript configuration and bootBuildImage
together, as well as caveats about launchScript that match the Maven
plugin documentation.

  Avoid using reflection when configuring Tomcat listener

This benefits native image building and AOT compilation,

Previously, regular bean definitions for configuration properties classes
that attempt to use constructor binding were detected in a bean factory
post-processor, ConfigurationPropertiesBeanDefinitionValidator. This
validation examined every standard bean definition and failed if it
encountered one for a class that should have used constructor binding.
There were two downsides to this approach:

1. Reflection used to identify if the bean should be using constructor
   binding triggered class loading that could prevent subsequent
   instrumentation by a load-time weaver.
2. The cost of the validation was incurred when there was no
   misconfiguration to report.

This commit replaces ConfigurationPropertiesBeanDefinitionValidator
with a failure analyzer. This failure analyzer only runs once a failure
has occurred and the application context is not going to complete
refresh. This avoids causing problems with subsequent instrumentation
and also avoids the cost of validation and error reporting unless there
is an error.

As of Spring Framework 5.3, it is now possible to use `PathPatternParser`
to parse and match request mapping path patterns, as an alternative to
the current default `AntPathMatcher`.

This new implementation has been used for a while in Spring WebFlux and
it’s been designed for consistency and performance.

This commit introduces a new configuration property for opting-in this
new variant:

`spring.mvc.pathmatch.matching-strategy=path_pattern_parser`

The default option is still `ant_path_matcher` for now, but we might
change the default in future versions since Spring Framework considers
it the best choice for modern applications.

There are several behavior differences with this new variant:

* double wildcards `"**"` are rejected when used in the middle patterns,
this is only allowed as the last matching segment in a pattern.

* it is incompatible with some path matching options, like
suffix-pattern, registered-suffix-pattern or configuring a Servlet
prefix on the `DispatcherServlet` (`spring.mvc.servlet.path=/test`)

This commit introduces two `FailureAnalyzer` implementations to guide
developers when facing those issues.
