Microsoft Visual Studio 2019 ships with LLVM/Clang 12 as of Visual
Studio 2019 16.11.0 (August 10, 2021). LLVM/Clang 12 is available on all
platforms. This change should make it easier to have clang-format "just
work" on dev systems and be consistent across platforms without having
to use an outdated version.
There are too many issues with 20.04 to successfully build with
VirtualCam - the azure kernel is missing videodev headers. For now,
use 18.04 LTS directly for main CI builds.
Both 18.04 and 20.04 include clang-format-10 without issue.
Batch files into clang-format to prevent needless processes. Now its
twice as fast in real time and uses 4x less resources. The old
implementation is also slower (but pretty close to) running a single
invocation of clang-format on all files.

Code formatting script was using `sysctl -n hw.physicalcpu` on macOS
machines to get the CPU count. This command returns the physical CPUs.
`nproc`, however, returns logical CPU count on Linux machines. It
should be `sysctl -n hw.logicalcpu` to make it consistent with its
Linux counterpart. But there also another way. `getconf
_NPROCESSORS_ONLN` gives the number of logical CPUs on both Linux and
macOS.
