[lsp] Bind lsp specific toggles from SPC m T to SPC m T l
Many lisp related modes create confliciting bindings in
`SPC m T`. To avoid these clashes I have moved the LSP
specific toggles to a different prefix now.

As this just affects toggles I hope that the negative
impact on muscel memory will be minimal.
