Update windows compilers

[h-vetinari]

Hey all

This feedstock is directly specifying vs2017_win-64 as a dependency,

sdl_image-feedstock/recipe/meta.yaml

Lines 18 to 22 in dff4a7d

	requirements:
	build:
	- {{ compiler('cxx') }} # [not win]
	- {{ compiler('c') }} # [not win]
	- vs2017_win-64 # [win64]

but should just rely on the {{ compiler('c') }} function to provide the correct compilers on windows. In particular, conda-forge has moved on to vs2019 as the default compiler a while ago already.

If you think you need vs2017, please let us know why (generally vs2019 and vs2022 should be fully compatible). If it's really necessary, please use the dedicated mechanism in conda_build_config.yaml for that, i.e.

c_compiler:     # [win]
  - vs2017      # [win]
cxx_compiler:   # [win]
  - vs2017      # [win]

as opposed to specifying it in meta.yaml directly.

I think the direct specification of vs2017 is a leftover from the past, let's see if just removing it works fine.

Thanks for the quick response!
