move cpr in-tree (#605)

* added cpr 1.10.5 in-tree to allow updates to vcpkg without breaking the build
* added asio 1.29.0 in-tree to remove one more vcpkg dependency
* bumped vcpkg to 2024.06.15 to address failure to build due to use of deprecated binaries in vcpkg (404 error: `https://mirror.msys2.org/mingw/mingw64/mingw-w64-x86_64-pkgconf-1~2.1.0-1-any.pkg.tar.zst` during build)

+## Formatting
+
+To avoid unproductive debates on formatting, this project uses `clang-format` to ensure a consistent style across all source files. Currently, `clang-format` 3.8 is the version of `clang-format` we use. The format file can be found [here](https://github.com/whoshuu/cpr/blob/master/.clang-format). To install `clang-format` on Ubuntu, run this:
+
+```
+apt-get install clang-format-3.8
+```
+
+To install `clang-format` on OS X, run this:
+
+```
+brew install clang-format
+```
+
+Note that `brew` might install a later version of `clang-format`, but it should be mostly compatible with what's run on the Travis servers.
+
+To run `clang-format` on every source file, run this in the root directory:
+
+```
+./format-check.sh
+```
+
+This should indicate which files need formatting and also show a diff of the requested changes. More specific usage instructions can be found on the official [LLVM website](http://releases.llvm.org/3.8.0/tools/clang/docs/ClangFormat.html).
