- lots of static_cast
- add safe_cast
- types adjustments
- config
- IStorage::read/watch
- ...
- some TODO's (to convert types in future)
P.S. That was quite a journey...
v2: fixes after rebase
v3: fix conflicts after #42308 merged

This makes the target location consistent with other auto-generated
files like config_formats.h, config_core.h, and config_functions.h and
simplifies the build of clickhouse_common.
For parts exchange right now an error message in stored in the
HTTPSession, via HTTPSession::attachSessionData(), and for each request
this HTTPSession::sessionData() is checked and if not empty printed into
the log.
However it should be reported only once, otherwise you will get this
message on and on, even for different tables. Here is an example of such
messages:
