MDBF-815 - HashiCorp Vault server

The scope of this PR is to create a separate Debian 12/i386 container image
with HashiCorp Vault installed.
Vault tests are part of the MBDF-815 requirements,
and the new fulltest-debug builder will use this image.

Changes to the BuildBot configuration will be done in a separate PR.
Built the image locally and tested on:
    Server version: 10.11.11
    Revision: c391fb1ff122adbfb9a7f98d3239aa08311918d6

# Create Debug build
cmake . -DCMAKE_BUILD_TYPE=Debug -DWITH_EMBEDDED_SERVER=1 \
-DHAVE_EMBEDDED_PRIVILEGE_CONTROL=1 -DWITH_DBUG_TRACE=OFF && make -j 24

# Start Vault server
vault server -dev > /dev/null 2>&1 &

# Run MTR with --suite=vault
cd mysql-test && perl mysql-test-run.pl --suite=vault \
--parallel=1 --verbose-restart --force --big
