Change explicit mention of Python binary to python3
which should be supported by all distributions and
environments (https://peps.python.org/pep-0394/).

Update hash bangs to python3.

Adapt CMake to search for pytest also as pytest-3; likewise
for nosetest binary as nosetests3 (with fallback to
pytest and nosetests, which can be used in some
virtual environments, even with a Python 3 install).

Remove unnecessary utf-8 encoding lines.

Update test scripts to python3

The `TObject::InheritsFrom` call can be quite slow. Since we already
deduce the object type (`TH1`, `TTree`, etc.) during registration, save
this information and use it instead of re-deriving it every time.
Also avoid calling `updateFiles` if no TTrees are registered.

Both these changes significantly speed up the `EndEvent` incident
handling for jobs with large (>10k) number of histograms.

Also re-organize `struct THistID` to avoid padding and delete unused
`reset` method.

In many-thread ATLAS jobs the lookup of that dictionary on every
THistSvc::updateFiles() call could lead to a significant bottleneck.
(As the dictionary lookup uses a mutex inside of the ROOT code.)

Fixes compilation warnings seen with gcc11.

In case no new file name was set, e.g. by not calling `io_update_all`,
do not try to open a file with an empty file name. This is a common
use-case in case the mother process is continuing to use its initial set
of ROOT files.

`TDirectory::mkdir` returns a `nullptr` in case the directory already
exists. This can happen in case the destination ROOT file already
exists.
