sfml: update from 3.0.2 to 3.1.0

[vSEK1RO]

meson.build files were carefully updated for examples and src directories, except for src/Network and src/Graphics.

• issue with Graphics is that harfbuzz and freetype have a circular dependency as mentioned here. sheenbidi doesn't have wrap, but the project itself uses meson. also, sheenbidi caused a lot of unused-function warnings.

• issue with Network is that mbedtls library doesn't have build scripts for meson.

i have tested with harfbuzz, freetype, mbedtls installed from the system (arch) and sheenbidi added using simple wrap-git, it worked.
