Update buildpack support to allow gzip compressed image layers to be
used when returned by the Docker engine. This update is restores
buildpack support when using Docker Desktop with the "Use containerd
for pulling and storing images" option enabled.
This commit introduces a new `ExportedImageTar` class to deal with the
intricacies of determining the mimetype of a layer. The class deals with
the parsing of `index.json' and related manifest blobs in order to
obtain layer information. The legacy `manifest.json` format is also
supported should `index.json` be missing.
Tests have been added to ensure that export archives from Docker Engine,
Docker Desktop (with and without containerd), and Podman can be used.

Update the regular expression used to parse Docker images references to
prevent catastrophic backtracking when images names are long and the
tag contains an illegal character.
See gh-39617
The logic to extract layers from a downloaded Docker image assumed that
the layer entries in the image tar archive always had the file extension
`.tar`. This was the case with Docker and other compatible daemons until
Docker 25.0. With this commit, the extension is no longer assumed, but
any entries listed in `manifest.json` will be recognized.
Fixes gh-39323
Update `PrivateKeyParser` implementations so that algorithm parameters
for PEM encoded 'EC PRIVATE KEY' files are loaded from the incoming
data.
Prior to this commit, the algorithm parameter was hard-coded to
'secp384r1' which could result in a mismatch to the actual file
content.
Fixes gh-34232
When building an image using the Maven `spring-boot:build-image` goal or
the Gradle `bootBuildImage` task, the build and launch caches can be
configured to use a bind mount as an alternative to using a named
volume.
Closes gh-28387
Configuration files managed by the Docker CLI are now used to determine
the host address of the Docker daemon used when building images using
buildpacks when a host address is not configured with environment
variables or build tool plugin configuration.
Closes gh-36445
