clang-format: re-format for clang-19

clang-format-19 isn't compatible with the clang-format-18 output, so we
need to reformat the code with the latest version. A few parameters
in clang-tidy have been deprecated, so adjust the style file
accordingly.

See Ie2f6eb3b043f2d655c9df806815afd7971fd0947 for updated style.
See I88192b41ab7a95599a90915013579608af7bc56f for clang-19 enablement.

asio: connection: Return unpacked value directly

`yield_method_call()` shall return the values of DBus methods, and it
was using constexpr if to check `sizeof...(RetTypes)` to get the return
type and construct default return values.

`message::unpack()` does the same thing so it is possible to return
directly.

In case of error occurs, it still need to return the default-constructed
value, so a helper function `default_ret_types()` is introduced for
default return in such case.

Handle timeouts in asio connections

It was reported in #98 that timeouts weren't working in some simple
cases. This appears to be because we've broken some of the assumptions
used by sd-bus around manually handling polling loops, and ignoring
sd_bus_get_timeout and sd_bus_get_events, as well as not calling
sd_bus_get_fd before every invocation. [1]

This commit:
Adds a steady_timer class to the asio object, which indirectly allows
expiring the underlying epoll loop early, based on the result of
sd_bus_get_timeout.

Changes the flow such that sd_bus_get_events is called and obeyed when
adding poll events to the reactor. While this wasn't seen in practice,
in theory we have the potential to miss events during heavy write loads
where the socket might block. This should resolve it.

Re-calls sd_bus_get_fd on each invocation of the poll loop, as directed
by the sd_bus documentation. Further testing is needed to see if this
resolves some of the match_t issues we've seen.

Tested: asio-example functions and prints expected content. More
in-system testing needed.

async: context: use new_bus by default

There are two primary methods for creating a generic bus:
* new_default
* new_bus

The "default" methods use TLS to get a shared bus for the thread. This
is likely not the desired bus to use for async operations because:

1. Currently a separate thread is used for the message processing.
2. Some existing synchronous code throughout openbmc uses
`new_default` instead of referencing an existing bus, which could
interfere with the async context.

Switch to using `new_bus` by default to ensure we get a fresh, unused
and unshared bus in the typical case.

The code was using a tuple to represent the multiple elements, and use
`r.read(responseData)` that would result in "Invalid Argument" error.

Fix it by `message::unpack` API to correctly read the response and
unpack the multiple elements into the tuple.
