tools: add sbom information for submodules

This adds SBOM information for submodules, which are not managed
by Espressif. Meaning there is no fork for them in the espressif
namespace. Other submodules should add sbom.yml manifest file to
the root of their git repository.

The SBOM information for submodules is stored in the .gitmodules file.
Each SBOM related variable has the "sbom-" prefix and the following
variables may be used:

sbom-version:
   submodule version

sbom-cpe:
   CPE record if available in NVD. This will be used by the SBOM
   tool to check for possible submodule vulnerabilities. The
   version in the CPE can be replaced with the "{}" placeholder,
   which will be replaced by the "sbom-version" value from above.

sbom-supplier:
   Person or organization who is providing the submodule.
   It has to start with "Person:" or "Organization:" prefix
   as required by the SPDX-2.2 standard.

sbom-url:
   URL to the project if exists, e.g. github.

sbom-description:
   Project description.

sbom-hash:
   Submodule SHA as recorded in the git-tree. This field is used by
   CI to check that the submodule checkout hash and info in .gitmodules
   are in sync. IOW if submodule is updated and it has SBOM info in
   .gitmodules, the .gitmodules has to be updated too. The test is
   part of this commit. The checkout has of the submodule can be found
   by using "git submodule status".

# Submodules SBOM information
# ---------------------------
# Submodules, which are used directly and not forked into espressif namespace should
# contain SBOM information here. Other submodules should have the SBOM manifest file
# included in the root of their project's repository.
#
# The sbom-hash entry records the submodule's checkout SHA as presented in git-tree
# commit object. For example spiffs submodule
#
# $ git ls-tree HEAD components/spiffs/spiffs
# 160000 commit 0dbb3f71c5f6fae3747a9d935372773762baf852 components/spiffs/spiffs
#
# The hash can be also obtained with git submodule command
#
# $ git submodule status components/spiffs/spiffs
# 0dbb3f71c5f6fae3747a9d935372773762baf852 components/spiffs/spiffs (0.2-255-g0dbb3f71c5f6)
#
# The submodule SHA recorded here has to match with SHA, which is presented in git-tree.
# This is checked by CI. Also please don't forget to update the submodule version
# if you are changing the sbom-hash. This is important for SBOM generation.
