refactor(lspsaga): use own kind table instead of catppuccin custom_kind

Drop the dependency on catppuccin's lsp_saga integration and define the
kind icons from the repo's own icons util (icons.kind / icons.type) with
LspKind* highlight groups, matching upstream ayamir/nvimdots.

Icons are now stable across colorschemes (only their LspKind* colors
follow the active theme via gen_lspkind_hl), and no catppuccin require is
needed, so the colorscheme guard added previously is no longer required.
