Move to JUnit 5 and Gradle 7

[MohammadAlHajj]

Dear Mr. Jones
please find the connected commits to the below repos:

• mantle-usl
• moqui-framework
• moqu-runtime

the goal of these commits is to move to Gradle 7.2 and to Junit 5

gradle 7:
changes need some

• more testing since i don't know if any more dependencies need to be changed to "java-library"'s 'api' dependency type or kept at gradle's built-in implementation type.
• These changes rely on the user's projects and which dependencies need their internals exposed to the user's projects.
• I also solved the known issue (noted in runtime > base-component > webroot > gradel.build):
  How to handle deprecated message related to Gradle 6.0 and the gradle-js-plugin ? eriwen/gradle-js-plugin#168
  by doing:
  Gradle 6.0.1 Build Failed eriwen/gradle-js-plugin#177 (comment)
• NOTE: the above project is probably dead and i highly advise the maintainer with the sufficient knowledge to find a replacement.... storing jars in the repo is obviously not an acceptable permanent solution
• Moving to gradle 7 allows the use of the newest Kotlin compiler in our projects and opens the door for moving to Java 11 or possibly java 17 whenit is released

JUnit5

• changes are none-intrusive since applying the new Jupiter and Vintage engines together allows both JUnit 4 and 5 tests to be run simultaneously..... It also separates the result of junit 4 tests into more readable chunks in Intellij (on running "gradle test"). Each test is now part of a subtree with the containing class as the new root of the test group
• Please note that i changed " ignoreFailures = true" since moqui (framework and usl) already has failing tests (on my project) and this blocks the execution of any further tests found in the user's module
