Display a warning when using Template Haskell and static binaries

[pepeiborra]

We know that HLS is likely to crash in this situation, specially in Mac OS, so perhaps HLS should use a WindowShowMessage LSP notification to warn the user and link to the documentation of the recommended solution, which is to build locally with dynamic linking.

The warning is shown if you build hls with --enable-executable-dynamic, but i thought that way th would also works.
With that flag the executable uses dybnamic linking for system libs but no for haskell dependencies (like --ghc-options="dynamic")
