Update `JarUrlConnection` and `NestedUrlConnection` so that calls
to `getLastModified()` and `getHeaderFieldDate("last-modified", 0)`
always return a result.

When an interrupted that calls FileChannel.read, the channel is
closed and the read fails with a ClosedByInterruptException. The
closure of the channel makes it unusable by other threads. To
allow other threads to read from the data block, this commit
recreates the FileChannel when a read fails on an interrupted
thread with a ClosedByInterruptException. The exception is then
rethrown to continue the thread's interruption.

Previously, the .class file for the renamed properties class was
on the class path of the compilation in two places:
1. The output directory of the test's previous compilation
2. The output directory of the compilation of src/test/java of
spring-boot-configuration-processor
The first of these locations is addressed by updating TestProject.
The .class file is now deleted from the project's output location
at the same time as the .java file is deleted from its source
location.
The second of these locations is addressed by configuring the class
path of the compiler to include a copy of the result of compiling
src/test/java of spring-boot-configuration-processor. From this copy
entries can then be deleted as needed without destabilizing other tests.

Fix issues with `DataBlockInputStream` including the fact that remain
bytes were not tracked correctly. Also add some tests and fix a few
other unusual details with the implementation.
Closes gh-38066
Update JarUrlConnection so that the full raw zip data is returned from
nested jars when no entry name is specified. This update allows
Tomcat's `WarURLConnection` to work with our nested connections since
they can parse the returned raw zip data.
Fixes gh-38047
The zip specification states that when 'bit 3' of the general purpose
flags is set then a data descriptor record must be present. Prior to
this commit, our `VirtualZipDataBlock` ignored such records and would
create invalid data.
Although the generated data would work for zip parsers that read the
central directory records, it causes problems with streaming reader
implementations such as `JarInputStream`.
This commit updates the code so that it now copies the data descriptor
records. It support both blocks that have a signature and those that
don't. It also updates the generation logic to correctly deal with
any extra data bytes present after the local file header record.
Fixes gh-38063
Update `UrlJarFileFactory` so that `runtimeVersion` is used by default
instead of `baseVersion`. Prior to this commit we tried to mirror the
JDK handler on look for a `#runtime` fragment. This unfortunately
doesn't work with the URLs produced by `URLClassPath`.
This commit also fixes a bug in `NestedJarFile` where we didn't return
the correct result from `hasEntry`.
Fixes gh-38050
Add a `NestedFileSystemProvider` implementation so that the JDK's
`ZipFileSystem` can load content from nested jars and nested
directory entries.
Creating a `ZipFileSystem` may be a relatively expensive operation as
zip structures need to be parsed and in the case of directory entries
a virtual datablock nees to be generated on the fly. As such, we
install the `ZipFileSystem` as late as possible since in a typical
application it may never be needed.
This commit also tweaks Gradle and Maven plugins to ensure that the
service loader file is written to repackaged jars.
Closes gh-7161
