Introduces a conanfile.py (and a Conan recipe for RocksDB) to enable building the package with Conan, choosing more recent default versions of dependencies. It removes almost all of the CMake build files related to dependencies, and the configurations for Travis CI and GitLab CI. A new set of cross-platform build instructions are written in BUILD.md.
Includes example GitHub Actions workflow for each of Linux, macOS, Windows.
* Test on macos-12
We use the <concepts> library which was not added to Apple Clang until
version 13.1.6. The default Clang on macos-11 (the sometimes current
version of macos-latest) is 13.0.0, and the default Clang on macos-12 is
14.0.0.
Closes#4223.
Clang warned about the code removed in this patch with the warning:
```
warning: out-of-line definition of constexpr static data member is
redundant in C++17 and is deprecated [-Wdeprecated]
```
There's a bug in gdb where unsigned template parameters cause issues with
RTTI. This patch changes a template parameter from `size_t` to `int` to
work around this gdb bug.
Reduce the reserve requirements from 20/5 to 10/2 in line with the current network votes. The requirements of 10/2 have been on the network long enough that new nodes should not still have the old reserve amount.

* Per actions/runner-images#6002, ubuntu-18.04 is being deprecated. If
latest ever fails in the future, we'll need to fix the jobs anyway, so
catch it early.
* Use long option names
* Force clang-format to ubuntu-20.04 because LLVM 10 is not available for 22.04
