Provide the 'flags' from the arguments of the create
command to the TransferList __init__ function.
This is so that the '--flags' argument to the tool is actually
used.

Relax entry addition from YAML files to allow the addition of
entries not known to the tool. It is not possible to keep track of
every possible TE, and a user might want to add an entry that hasn't
yet been specified.

Add void entries to ensure proper alignment of data in the TL,
addressing runtime errors caused by previously unaccounted padding bytes
between TE's.

Fix the handoff 8-bit modulo checksum calculation to ensure we never get
a checksum larger than 8 bits. The previous calculation failed to
truncate the sum at the final step in update_checksum

To facillitate our testing, add some fixtures to make it easier to
generate transfer entry data.

Introduce the gen-header command to the tool, enabling developers to
create language bindings. Currently, it supports generating C headers
from a transfer list.

Add tox to automate testing across multiple environments, ensuring code
robustness and compatibility with different Python versions. This helps
ensure consistency in test environments so both development and CI
systems run tests uniformly, and simplifies the execution of tasks like
linting and other commands with a single command.

This commit adds a command create-from-yaml to tlc, which
creates a transfer list from a yaml file. It also changes
the files structure of the fixtures in the unit tests so
they are in a directory called trusted-firmware-a. This
is necessary because blob file paths in the yaml file are
relative to the root of TF-A.
The blob files are not verified by TLC, so it can be used
to load arbitrary binary information into the transfer
list. The authenticity of the transfer list must be
ensured by the loader.

This makes the build reproducible.
When `make dev-install` was run, it would ignore the existing
poetry lock file, install different versions of all the
libraries, then overwrite the lock file. Once `--no-update`
is added, it stops doing that, and installs exactly what is
in the poetry lock file.

Transfer List Compiler is a command line tool that enables the static
generation of TL's compliant with version 0.9 of the firmware handoff
specification. The intent of this tool is to support information passing
via the firmware handoff framework to bootloaders that run without
preceding images (i.e. `RESET_TO_BL31`).
It currently allows for TL's to be statically generated from blobs of
data, and modified by removing/adding TE's. Future work will provide
support for TL generation from configuration file.
