Update build environment Dockerfile with latest static analysis tools

[jpswinski]

The code supports running with the latest clang-tidy and cppcheck from the Ubuntu 24.04 packages, but the default packages in AL2023 do not have the latest version of these tools. As a result, the docker build environment does not run the latest checks, while our personal development machines do.

In order to run the latest static analysis, the Dockerfile.buildenv file needs to be updated to build the clang-tidy and cppcheck tools from source:

# install up-to-date llvm tools (clang-tidy)
RUN git clone https://github.com/llvm/llvm-project.git && \
    cd llvm-project && \
    git checkout llvmorg-18.1.5 && \
    mkdir -p /llvm-project/build && \
    cd /llvm-project/build && \
    cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" /llvm-project/llvm && \
    make -j8 && \
    make install

# install up-to-date cppcheck
RUN git clone https://github.com/danmar/cppcheck.git && \
    cd cppcheck && \
    git checkout 2.14.0 && \
    mkdir -p /cppcheck/build && \
    cd /cppcheck/build && \
    cmake -DCMAKE_BUILD_TYPE=Release -DMATCHCOMPILER -DHAVE_RULES -DCXXFLAGS="-O2 -DNDEBUG -Wall -Wno-sign-compare -Wno-unused-function" .. && \
    make -j8 && \
    make install
