drop legacy support

From this release, esmock now supports minimum node version 22.15. Changes here are mostly credit to @​tommy-mitchell.

Older versions of esmock supported numerous different scenarious as required by legacy versions of nodejs, which added complexity and noise to source code, to bundling operations and to unit-tests. As a result of dropping support for older node versions, esmock's install size is smaller than ever, ~20.5Kb; its CI test-coverage is higher than ever, 100%, its test pipeline finishes sooner and its source code is more readable.

• streamline and update test-suite. remove logic to run "--loader" and non-"--loader" specific tests. remove logic to run or skip tests for specific (older) versions of node. remove logic to run or skip tests depending upon windows or linux environment. remove un-maintained testing-tools from the test suite: ts-node, tsm and uvu. greatly simplifies the tests
• drop support for pre-v20 node --loader behaviour. removal of some code that was un-usual and un-intuitive. removes mention of "--loader" from README.md for slightly smaller README.md,
• drop all support for node v20 and earlier, credit @​tommy-mitchell
• publish a single minified file. previous versions published separate loader and loader.deprecated files. npm publish --dry-run shows smaller package-size @​v3.0.0 8.4 kB (was @​v2.8.0 10.3 kB),
• support simultaneous local and global import mocks. Previously, local and global import mocks sharing the same name would resolve the global variant. credit @​tommy-mitchell, thank you
