Fix buffer_copy

boost::asio::buffer_copy returns an integer of the number of values
copied. Some static analysis tools mark that value as nodiscard,
although it should never fail. Audit all uses of buffer_copy, and make
sure that they're using the return value. In theory this should have
no change on the behavior.

Fix SSE sockets

Redfish protocol validatator has SSE tests that expose some bad coding
practies in SSE handlers, namely, that there are several cases where we
don't check for nullptr.

Fix them.

This appears to have been introduced in:
https://gerrit.openbmc.org/c/openbmc/bmcweb/+/41319

Tested: Redfish service validator passes more tests.

Rename FileBody to HttpBody

Now that our custom body type does things more than files, it makes
sense to rename it. This commit renames the header itself, then all
instances of the class.

Add unit test for SSE

Writing this test exposed some bugs in SSE that got merged.
sendSSEHeader was never called, leading to a connection that starts
and immediately closes with no error code.

This issue has been corrected in code, such that the sockets start.

To allow for unit tests, the io_service needs to be passed into the
class, previously, the SSE connection was pulling the io_context from
the DBus connection, which is odd, given that the SSE connection has
no other dependencies on DBus.

Unit tests should help keep it working.

Tested: Unit tests pass.

Replace logging with std::format

std::format is a much more modern logging solution, and gives us a lot
more flexibility, and better compile times when doing logging.

Unfortunately, given its level of compile time checks, it needs to be a
method, instead of the stream style logging we had before. This
requires a pretty substantial change. Fortunately, this change can be
largely automated, via the script included in this commit under
scripts/replace_logs.py. This is to aid people in moving their
patchsets over to the new form in the short period where old patches
will be based on the old logging. The intention is that this script
eventually goes away.

The old style logging (stream based) looked like.

BMCWEB_LOG_DEBUG << "Foo " << foo;

The new equivalent of the above would be:
BMCWEB_LOG_DEBUG("Foo {}", foo);

In the course of doing this, this also cleans up several ignored linter
errors, including macro usage, and array to pointer deconstruction.

Note, This patchset does remove the timestamp from the log message. In
practice, this was duplicated between journald and bmcweb, and there's
no need for both to exist.

One design decision of note is the addition of logPtr. Because the
compiler can't disambiguate between const char* and const MyThing*, it's
necessary to add an explicit cast to void*. This is identical to how
fmt handled it.

Tested: compiled with logging meson_option enabled, and launched bmcweb

Saw the usual logging, similar to what was present before:
```
[Error include/webassets.hpp:60] Unable to find or open /usr/share/www/ static file hosting disabled
[Debug include/persistent_data.hpp:133] Restored Session Timeout: 1800

Add Server-Sent-Event support

Server-Sent-Event is a standard describing how servers can initiate
data transmission towards clients once an initial client connection has
been established. Unlike websockets (which are bidirectional),
Server-Sent-Events(SSE) are unidirectional and commonly used to send
message updates or continuous data streams to a browser client.

This is base patch for adding Server-Sent-Events routing support to
bmcweb. Redfish EventService SSE style subscription uses SSE route for
sending the Events/MetricReports to client which establishes the
connection.

Tested this patch with along with EventService SSE support patches and
verified the functionalty on browser.

Tested:
- Tested using follow-up patches on top which adds
support for Redfish EventService SSE style subscription
and observed events are getting sent periodically.
- Created SSE subscription from the browser by visiting
https://<BMC IP>/redfish/v1/EventService/SSE
