Update SDL2_ttf to 2.22.0

[thevenin90]

Please update the SDL2_ttf library to 2.22.0
2.0.18 introduced TTF_Measure* functions.
2.20.0 introduced LCD rendering functions.
This will also keep the Julia bindings up to date with the documentation. I was wondering why I couldn't use the Measure and LCD functions until I realized SDL2_ttf_jll was stuck on version 2.0.15

You can do it yourself by submitting a PR to update the version. On the first instance you need to update the version number

Yggdrasil/S/SDL2_ttf/build_tarballs.jl

Line 6 in c98ffc7

version = v"2.0.15"

and the commit hash

Yggdrasil/S/SDL2_ttf/build_tarballs.jl

Line 11 in c98ffc7

"a9eceb1ad88c1f1545cd7bd28e7cbc0b2c14191d40238f531a15b01b1b22cd33"),

and then deal with all possible issues
