Extract `ErrnoException` into `Common/ErrnoException.h` to reduce the
include footprint of `Exception.h`. This removes `<base/errnoToString.h>`
and `<cerrno>` from `Exception.h`, which is included by ~95% of all
translation units.
All files referencing `ErrnoException` now include the new header
directly. Files that used `errnoToString` without `ErrnoException`
got an explicit `<base/errnoToString.h>` include.

- Add --group option to start and restart commands
- Use clickhouse su instead of sudo when --no-sudo is set
- Pass --prefix, --pid-path, --config-path, --binary-path, --user, --group
from install to the suggested start/restart command

This commit improves the help output for all ClickHouse applications:
- Add `clickhouse help` command that lists all available subcommands
- Return exit code 0 for all help messages (previously some returned 1)
- Output help messages to stdout instead of stderr
- Use "clickhouse <cmd>" format instead of argv[0] in help messages
- Add dynamic `app_name` detection for `clickhouse client` and `clickhouse local`
to show correct invocation name based on how the binary was called
- Add `--no-sudo` option for `clickhouse start` and `clickhouse restart`
for environments without sudo (e.g., Docker containers)
- Add detailed help headers and footers for client and local with usage examples
Closes#58244

Previously it was only shipped as part of the client package, now it
will be bundled into the binary, and will be available as:
- clickhouse chdig
- clickhouse-chdig
- chdig
Note, that since now chdig will not be linked, we can remove all
quirks for this, that has been done in #79666
Components like client/server/... are very generic, and there is no
point in disabling them, since it does not reduce amount of compiled
code a lot anyway (just a few modules for entrypoints, everything else
is already included in the clickhouse binary), and eventually they are
just symlinks to the clickhouse binary.
But there are few, that requires extra libraries, like ODBC bridge or
keeper components (and there is also standalone keeper binary compiled
with musl), those had been kept.
Also add some descriptions for some utils and change exit code to 0 for
--help.

- 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
