Verify all added plugin dependencies are reflected in plugin descriptors

[YannCebron]

Describe the need of your request

Any dependency on bundled/external plugin must be defined in plugin descriptor (https://plugins.jetbrains.com/docs/intellij/plugin-dependencies.html#3-dependency-declaration-in-pluginxml).

Unfortunately, many users miss this step which leads to NCDFE at runtime.

Proposed solution

In verifyPluginProjectConfiguration task, check that each defined plugin ID from build script occurs at least once in any of the plugin descriptors of the final plugin distribution.
