instead of hardwiring the toolchain image in github workflows, read it
from `tools/toolchain/image`. a dedicated reusable workflow is added to
read from this file, and expose its content with an output parameter.
also, switch iwyu.yaml workflow to this image, more maintainable this
way. please note, before this change, we are also using the latest
stable build of clang, and since fedora 40 is also using the clang 18,
so the behavior is not change. but with this change, we don't have
the flexibility of using other clang versions provided
https://apt.llvm.org in future.

to cover more directories to prevent regressions of violating
the "include what you use" policy in this directory.

before this change, user has to click into the "Details" link for
access the report from clang-include-cleaner. but this is neither
convenient nor obvious.
after this change, the report is annotated in the github web interface,
this helps the reviewers and contributers to user this tool in a
more efficient way.

clang-include-cleaner actually interprets the preprocessor macros,
and looks at the symbols. so we have to prepare the included headers
before using it.
so, but in ScyllaDB, we don't have a single target for building all the
used headers, so we have to build them either in batch of separately.
in this change, we build the included headers before running
clang-include-cleaner. this allows us to run clang-include-cleaner on
more source files.

iwyu is short for "include what you use". this workflow is added to
identify missing "#include" and extraneous "#include" in C++ source
files.
This workflow is triggered when a pull request is created targetting
the "master" branch. It uses the clang-include-cleaner tool provided
by clang-tools package to analyze all the ".cc" and ".hh" source files.
