chore: remove obsolete Haxe versions

[moxie-coder]

I also bumped Haxe 4.3.2 to 4.3.7 as that’s now the latest release but I could revert that back. I don’t expect this to be merged for a few reasons in mind

I understand 3.4.7, but I'm curious why you removed 4.0.5 too. If anything, I've personally found that 4.0 is often less work to support than 4.1 because 4.1 tends to be weirdly more strict about certain types of syntax than both its surrounding 4.0 and 4.2.

Note: We'll likely wait to remove 3.4.7 support from libraries like Away3D and Starling until after Lime and OpenFL drop support for this version too. This is likely to happen at some point after Haxe 5.0 is released, whenever that ends up happening.

sorry I just got back from vacation, but I reverted it!
