Johnni Winther 56f46b0659 Remove non-nullable experiment flag from front_end test cases.
This changes the CFE expectation test suites to use unsound null safety
as default to avoid passing --enable-experiments=no-non-nullable to opt
out old test folders.

This change removes most test folders from the 'strong' tester, since
this now only supports sound null safety, which requires all libraries
to be opted in. Instead, the 'weak' tester now runs all test folders.
Additionally the 'outline' tester is changed to use unsound null safety
so that it call be used on all test folders.

The 'fast_strong' tester is removed since it should just be run locally
and it can be run by passing an option to the other testers.

References to non-existing 'shaker' folder has been removed from
testing.json.

/**
* @assertion Execution of a case clause case ek: sk of a switch statement
* switch (e) {label11 ..label1j1 case e1: s1 … labeln1 ..labelnjn case en: sn default: sn+1}
* proceeds as follows:
* The expression ek == id is evaluated to an object o which is then
* subjected to boolean conversion yielding a value v.
* If v is not true, the following case, case ek+1: sk+1 is executed if it exists.
* If case ek+1: sk+1 does not exist, then the default clause is executed by executing sn+1.
* If v is true, let h be the smallest integer such that h >= k and sh is non-empty.
* If no such h exists, let h = n + 1. The sequence of statements sh is then executed.
* If execution reaches the point after sh then a runtime error occurs, unless h = n + 1.
* @description Checks that falling through produces a runtime error, unless
* the current clause is an empty case clause or the default clause.
