Slf4j2 bridge

Fixes: #567

slf4j bridge for slf4j v2

few notes:

• new module zio-logging-slf4j2-bridge as zio-logging-slf4j-bridge is for slf4j v1, do we want to change naming for modules? For example have zio-logging-slf4j-bridge for actual version - v2, and for v1 have zio-logging-slf4j1-bridge or something else
• slf4j v2 using JDK9+ module system (JPMS) see: slf4j v2 changes, this currently introduced few problems, as sbt have unresolved JPMS support:
  • sbt jpms issue: JDK9: Support module-info.java sbt/sbt#3368
  • sbt-jpms plugin prototype
  • in relation to mentioned sbt JPMS issue, following steps were applied:
    • compileOrder := CompileOrder.JavaThenScala setting (mentioned in sbt issue) worked, but in this case java classes, can not use scala classes, code was implemented in that way
    • javacOptions and javaOptions dependencies with --module-path
    • there is issue with scala doc in relation to JPMS module, scala doc artifact publishing is disabled now
