build: Clean up client CMake

These were used to make code migration smoother (to the new lib_system and lib_domain)

* spark/algorithm/TryCatch.h -> system/algorithm/try_catch.h
* spark/core/BoolName.h -> system/bool_name.h
* spark/core/EnumMacros.h -> system/enum_macros.h
* spark/core/FMT.h -> system/FMT.h
* spark/core/FMT_IMPL.h -> system/FMT_IMPL.h
* spark/core/TimeSpan.h -> system/time_span.h
* spark/core/TimeStamp.h -> system/time_stamp.h
* spark/domain/Price.h -> domain/price.h
* spark/io/JsonReader.h -> system/json/json_reader.h
* spark/io/JsonDumper.h -> system/json/json_dumper.h
