Improve Ender-3 with SKR Mini E3 V3 Config

Benefits

Bring config more in line with other SKR Mini E3 configs

[cbagwell]

I aligned my config file with these changes and tested them and all went fine. A few notes.

• These changes apply to Ender 3 Pro config in case you want to update that set as well (what I tested).
• I left endstop interrupt enabled because its worked well for me so far.
• I didn't test BLTOUCH changes since mine is connected to 5-pin connector. Perhaps that reduced my risk of misconfiguring BLTOUCH and leading to endstop issue as mentioned in that other issue.
• I didn't test the PID values.

These changes apply to Ender 3 Pro config

@cbagwell — Every change without exception? What is the primary difference with the Ender-3 Pro over the Ender-3?

Better PSU

What is the primary difference with the Ender-3 Pro over the Ender-3?

As far as Marlin is concerned? Basically nothing.

Pro configs say “Ender-3 Pro” on the status screen “Ready” message and _Statusscreen.h.

I'd almost forgotten about that import status screen. 😄 The Pro also comes with a magnetic bed instead of using clips but there are no features enabled that require knowledge of that (no probe for example). And I noticed even non-Pro is starting to ship with magnetic beds depending where you purchase and I wouldn't be surprised if they are totally the same as Pro's now since even the Pro no longer ships with a Meanwell PSU.

The lines between Ender-3 SKUs are quite blurred at this point.

We'd have a lot more Ender-3 Pro configs if we:

• Back up the Ender-3 Pro's _Statusscreen.h
• Nuke the contents of the Ender-3 Pro configs folder
• Copy over Ender-3 configs & replace previously backed up _Statusscreen.h
• Replace all mentions of "Ender-3" with "Ender-3 Pro"

...Then remember to always add an Ender-3 Pro config for each new Ender-3 config. Or automate it.

We'd have a lot more Ender-3 Pro configs…

Sounds like all that could be done with a README that explains the Ender-3 Pro is just the Ender-3 with some settings and files adjusted. But, if all Ender-3 configs were ported over to Ender-3 Pro configs it wouldn't be a major addition to the existing maintenance burden, as we're already doing "mostly automated" maintenance of over 300 configs now.
