feat: Use dynamic import for external JS

[Nerivec]

• Replace node:vm logic with dynamic importing
• Allow .js, .cjs and .mjs code
• [live-reload] Version file naming on MQTT save when file already exists (also allows to bypass node module caching)
• Update typing
• Add MJS-specific tests
• Update test sample converters to use importing for better representation
• Skip and relocate invalid external JS on Z2M start

TODO:

• docs for Koenkk/zigbee2mqtt#26522 zigbee2mqtt.io#3602
• fix loading latest version only from file system
  • alternative to versioning to bypass module caching?
• handle removing old versions
• fix: Generated source for Koenkk/zigbee2mqtt#26522 zigbee-herdsman-converters#9003

With the error handling now moving invalid files to the old directory (prevents constantly messing with Z2M and avoids extra code to bypass them everywhere), I'm thinking the contents of the old directory shouldn't be rotated by Z2M. It's not like there will be a lot of iterations by most users. Plus the archiving is only triggered when live-editing via MQTT, which is unlikely to be the favored option anyway.
