Toolchain+Docs: Improve the way to enable clangd

Browse source 
Allowing an environment variable to enable/disable the build for clangd
and other toolchains will improve the developer-experience than
reconfiguring and building the toolchain manually.

Now you will have to call the command as following
	$ CLANG_ENABLE_CLANGD=ON Toolchain/BuildClang.sh

the script. Pointing your editor's plugins to the custom-built clang tools and a ``compile_commands.json`` from a clang build
of Serenity can enable richer error reporting than the tools that are installed for the build host.
To enable building clangd as part of the clang toolchain, set ``CLANG_ENABLE_CLANGD`` to ON in
``Toolchain/CMake/LLVMConfig.cmake`` before running BuildClang.sh. If you already built the clang toolchain and would like to
enable the custom clangd build, change the CMake cache variable ``CLANG_ENABLE_CLANGD`` to ON in ``Toolchain/Build/clang/llvm``
and re-install with ``cd Toolchain/Build/clang/llvm && cmake ../../../Tarballs/llvm-project-$LLVM_VERSION.src/llvm -DCLANG_ENABLE_CLANGD=ON && ninja install/strip``, where $LLVM_VERSION should be tab-completable in your shell.
To enable building clangd as part of the clang toolchain, set ``CLANG_ENABLE_CLANGD`` environment variable to ``ON``, then run ``Toolchain/BuildClang.sh``.
