Look into changing the way we include the compiler plugin

[ckipp01]

Currently we are actually just including both the scalac-scoverage-runtime and the scalac-scoverage-plugin as library dependencies. Then we later check the dependencies to see if it's there, grab the location of the compiler plugin, and then include it with -Xplugin.

sbt-scoverage/src/main/scala/scoverage/ScoverageSbtPlugin.scala

Line 79 in 37258c6

Some(s"-Xplugin:${pluginPath.getAbsolutePath}"),

I'm trying to get a bit more familiar with anything before making any real changes, but I believe we instead might be able to just utilize addCompilerPlugin to make this a bit easier.

That's probably the same thing just shorter. I would test it by making the change and comparing the resulting scalac command line, either with export compile or with a task manager like ps while it's running.

One difference is IIRC addCompilerPlugin may set the dependency scope. What config is in the current libraryDependencies setting?
