Add `static` to file-local functions and forward declarations
for cross-TU functions to satisfy `-Wmissing-prototypes`.
This ensures all functions have visible prototypes before their
definitions, improving code quality and catching accidental
linkage issues.

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.

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

Converted usage of CH-custom bit_cast to std::bit_cast if possible, i.e.
when
sizeof(From) == sizeof(To).
(The CH-custom bit_cast is able to deal with sizeof(From) != sizeof(To).)
Motivation for this came from #42847 where it is not clear how the
internal bit_cast should behave on big endian systems, so we better
avoid that situation as much as possible.
