sail: Fix compilation with shared=True

[perseoGI]

Summary

Changes to recipe: sail

• Bump libavif to fix linkage issues against yuv and libwebp
• conan v2 refactor

Motivation

When building sail as shared and their dependencies as static, following error appears:

$ conan create recipes/sail/all --version 0.9.6  --build=missing -o '&:shared=True'
...

New patches aim to modify sail-codecs/jpegxl/CMakeLists.txt to use a standard find_package instead of custom find library logic.
This way conan libjxl can be found by project.

Also, other errors have been found when the previous error were solved:

Undefined symbols for architecture arm64:
  "_SharpYuvConvertWithOptions", referenced from:
      _avifImageRGBToYUVLibSharpYUV in libavif.a[13](reformat_libsharpyuv.c.o)
  "_SharpYuvOptionsInitInternal", referenced from:
      _avifImageRGBToYUVLibSharpYUV in libavif.a[13](reformat_libsharpyuv.c.o)

This error exists in every sail version compiling statically or shared.
Can be fixed bumping libavif dependency to a newer one, as upstream does in their CI downloading the latest version from homebrew. See upstream code.

Minor changes made, removed conan v1 old logic.

Fix #25807
