Build: Shadow x-pack:protocol into x-pack:plugin:core (#32240)

This bundles the x-pack:protocol project into the x-pack:plugin:core
project because we'd like folks to consider it an implementation detail
of our build rather than a separate artifact to be managed and depended
on. It is now bundled into both x-pack:plugin:core and
client:rest-high-level. To make this work I had to fix a few things.

Firstly, I had to make PluginBuildPlugin work with the shadow plugin.
In that case we have to bundle only the `shadow` dependencies and the
shadow jar.

Secondly, every reference to x-pack:plugin:core has to use the `shadow`
configuration. Without that the reference is missing all of the
un-shadowed dependencies. I tried to make it so that applying the shadow
plugin automatically redefines the `default` configuration to mirror the
`shadow` configuration which would allow us to use bare project references
to the x-pack:plugin:core project but I couldn't make it work. It'd *look*
like it works but then fail for transitive dependencies anyway. I think
it is still a good thing to do but I don't have the willpower to do it
now.

Finally, I had to fix an issue where Eclipse and IntelliJ didn't properly
reference shadowed transitive dependencies. Neither IDE supports shadowing
natively so they have to reference the shadowed projects. We fix this by
detecting `shadow` dependencies when in "Intellij mode" or "Eclipse mode"
and adding `runtime` dependencies to the same target. This convinces
IntelliJ and Eclipse to play nice.

+### Gradle Build
+
+We use Gradle to build Elasticsearch because it is flexible enough to not only
+build and package Elasticsearch, but also orchestrate all of the ways that we
+have to test Elasticsearch.
+
+#### Configurations
+
+Gradle organizes dependencies and build artifacts into "configurations" and
+allows you to use these configurations arbitrarilly. Here are some of the most
+common configurations in our build and how we use them:
+
+<dl>
+<dt>`compile`</dt><dd>Code that is on the classpath at both compile and
+runtime. If the [`shadow`][shadow-plugin] plugin is applied to the project then
+this code is bundled into the jar produced by the project.</dd>
+<dt>`runtime`</dt><dd>Code that is not on the classpath at compile time but is
+on the classpath at runtime. We mostly use this configuration to make sure that
+we do not accidentally compile against dependencies of our dependencies also
+known as "transitive" dependencies".</dd>
+<dt>`compileOnly`</dt><dd>Code that is on the classpath at comile time but that
+should not be shipped with the project because it is "provided" by the runtime
+somehow. Elasticsearch plugins use this configuration to include dependencies
+that are bundled with Elasticsearch's server.</dd>
+<dt>`shadow`</dt><dd>Only available in projects with the shadow plugin. Code
+that is on the classpath at both compile and runtime but it *not* bundled into
+the jar produced by the project. If you depend on a project with the `shadow`
+plugin then you need to depend on this configuration because it will bring
+along all of the dependencies you need at runtime.</dd>
+<dt>`testCompile`</dt><dd>Code that is on the classpath for compiling tests
+that are part of this project but not production code. The canonical example
+of this is `junit`.</dd>
