[MBUILDCACHE-123] remove duplicated codes by adding field cacheState to MojoParametersListener

[zrlw]

Even maven build cache extension is already enabled, MojoParametersListener#beforeMojoExecution needs to set projectExecutions only when source == Source.LIFECYCLE && !forkedExecution is true.
The most appropriate way to handle MBUILDCACHE-123 is adding field cacheState to MojoParametersListener and setting it's value by BuildCacheMojosExecutionStrategy.

Following this checklist to help us incorporate your
contribution quickly and easily:

• Make sure there is a MBUILDCACHE JIRA issue filed
  for the change (usually before you start working on it). Trivial changes like typos do not
  require a JIRA issue. Your pull request should address just this issue, without
  pulling in other changes.
• Each commit in the pull request should have a meaningful subject line and body.
• Format the pull request title like [MBUILDCACHE-XXX] - Fixes bug in ApproximateQuantiles,
  where you replace MBUILDCACHE-XXX with the appropriate JIRA issue. Best practice
  is to use the JIRA issue title in the pull request title and in the first line of the
  commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Run mvn clean verify to make sure basic checks pass. A more thorough check will
  be performed on your pull request automatically.
• You have run the Core IT successfully.
