Now that Git is a bit stricter when compiling its own source, we need to exempt mimalloc a bit more. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
Instead of trying to "fix" whitespace issues in mimalloc's source, thereby making it unnecessarily complicated to keep the vendored-in mimalloc sources in sync, let's just prevent Git from trying to enforce its coding style rules on said vendored-in source files.

In preparation for upgrading to a newer mimalloc version; This patch will not be needed anymore, as it has been implemented in a slightly different form in upstream mimalloc: 3e1d800e (potential fix for windows static linking with thread creation in dll's, 2022-11-07).

We want to compile mimalloc's source code as part of Git, rather than requiring the code to be built as an external library: mimalloc uses a CMake-based build, which is not necessarily easy to integrate into the flavors of Git for Windows (which will be the main benefitting port).

In the meantime, v2.2.3 was released. I meant to update this PR but ran out of time. |

To support mimalloc-enabled builds also on Linux and on macOS, we need to ship the respective backends, too. This helped me diagnose "mimalloc vs reftable" problems much quicker because Git's birthplace *is* Linux, and its support for debugging on that platform is still highly unmatched by its support for any other platform. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
Let's ignore the `static void mi_stat_total_print()` function that is not actually used. This is code vendored into Git, and we want to deviate as minimally from upstream mimalloc as possible to make it cheap to stay up to date. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

Git for Windows still carries [mimalloc v2.1.2](https://github.com/microsoft/mimalloc/releases/tag/v2.1.2), which is almost 2 years old. Let's upgrade.
