03c2660f75 fix(tlc): add void entries to align data
Add void entries to ensure proper alignment of data in the TL,
addressing runtime errors caused by previously unaccounted padding bytes
between TE's.

5ca0241c7a fix(handoff): correct 8-bit modulo csum calculation
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.

9b05c3739c feat(tlc): add command gen-header
Introduce the gen-header command to the tool, enabling developers to
create language bindings. Currently, it supports generating C headers
from a transfer list.

311209934e feat: add creating transfer lists from yaml files
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.

6ac31f3e76 feat(tlc): add host tool for static TL generation
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.
