add missing headers for new toolchain

[huww98]

These are necessary for compiling with Ubuntu 24.04 default toolchain/boost.

Greate job! I've tried to run this on Ubuntu 24.04, facing a lot of issues. I eventually failed because I cannot install the RDMA driver. But I don't want to waste my work. So here is part of my modifications to make it compile.

• add fmt:: namespace to distinguish from std::format_to #43
• robin hood: resolve warning on new clang #44
• Remove unused dependency libprocps #45
• explicit down cast #46

With these change, plus some changes to third_party, I'm able to build this on Ubuntu 24.04, with -Werror removed and google/leveldb#1255, ClickHouse/clickhouse-cpp#296, facebook/rocksdb#11118
