Remove legacy test utils (#957)
* Delete legacy-utils.ts * Updated some test suites to use new testbuilder * Added module capabilities to testbuilder * Fixed more test cases * Updated remaining test cases that used legacy utils * Fixed unused variable * Fix prettier * Fixed remaining tests Fixed function assignment test according to discord discussion (https://discord.com/channels/515854149821267971/600291243523702805/800403280512417792) Fixed hoisting by hardcoding the expected value, because the current TestBuilder.executeJS() setup does not handle module hoisting * Addressed review comments * Addressed 2nd review
