Upgrade fmt from 10.2.1 to 11.2.0

[afarber]

Fix #7238 by:

• Upgrade fmt dependency from 10.2.1 to 11.2.0 using git rm -r third_party/fmt && git subtree add --prefix=third_party/fmt https://github.com/fmtlib/fmt.git 11.2.0 --squash to preserve the upstream git log. This is necessary, because the upstream fmt project has switched from using a branch (like 10.x) to using tags on the master branch and thus git subtree pull would not work
• Add /utf-8 flag for MSVC to satisfy fmt 11.2.0 Unicode requirement
• Update obsolete link in scripts/update_dependencies.sh comment
• Ignore .gradle folder

Tasklist

Hi @DennisOSRM and @SiarheiFedartsou please review my PR.

Naturally it modifies many files.

You can verify, that I have not introduced any "trojan horses" by running:

git clone --depth 1 --branch 11.2.0 https://github.com/fmtlib/fmt.git /tmp/fmt-official

for dir in include src CMakeLists.txt; do
  echo "=== Comparing $dir ==="
  diff -r "third_party/fmt/$dir" "/tmp/fmt-official/$dir" \
    --exclude='*.o' --exclude='*.so' --exclude='CMakeFiles' \
    --exclude='*.cmake' --exclude='Makefile' 2>/dev/null || echo "No differences"
done
