Drop support for EdgeHTML browser using -sMIN_EDGE_VESRION (#20881)
This browser was replaced with the chromium-based Edge back in 2018: https://blog.mozilla.org/en/mozilla/goodbye-edge/ According to https://www.statista.com/statistics/545520/market-share-of-internet-browsers-usa/ Edge Legacy accouts for just 0.05% of the browser market.

-----------------------
23+
- Support for explicitly targeting the legacy EdgeHTML browser (edge version
24+
prior to the chromium-based edge) via `-sMIN_EDGE_VERSION` was removed.
25+
Using `-sLEGACY_VM_SUPPORT` should still work if anyone still wanted to target
26+
this or any other legacy browser.
2327
- Breaking change: Using the `*glGetProcAddress()` family of functions now
2428
requires passing a linker flag -sGL_ENABLE_GET_PROC_ADDRESS. This prevents
2529
ports of native GL renderers from later accidentally attempting to activate
