Split compiler bridge tests to another subproject

Splitting compiler bridge tests to another subproject because while the bridge itself can be compiled with just compiler-interface, util-interface, and Scala Compiler as dependencies, the testing introduces more (such as IO). This creates problem for new Scala versions where IO or test libraries do not exist yet (e.g. Scala 2.13.0-M2). This also removes the Mima test due to the lack of 2.13 bridge for Zinc 1.0.0. Compiler bridge just needs to compile itself against the interface and Scala compiler, so there's no need to run Mima test.
