Completely rework ensure_installed

Is your feature request related to a problem? Please describe.

One of the biggest pain points of Mason is being able to auto install language servers. Mason has an ensure_installed flag to auto install them but the way it works I can't figure out and seems overly convoluted.

For example, I wanna install the dart language server. In the TUI Mason popup when typing :Mason, it's called "dcm". Okay, so I should just be able to add dcm into ensure installed right?

   1 return {
    2  "mason-org/mason-lspconfig.nvim",
    3  opts = {},
    4  dependencies = {
    5   { "mason-org/mason.nvim", opts = {} },
    6   "neovim/nvim-lspconfig",
    7  },
    8  config = function()
    9   local ok, mlsp = pcall(require, "mason-lspconfig")
   10   if not ok then
W  11    vim.notify("mason-lspconfig not found")
   12    return
   13   end
   14
   15   mlsp.setup({
   16    ensure_installed = {
   24     "dcm",
   38    },
   39    automatic_installation = true,
   40   })
   41  end
   42 }

Well this doesn't work. Because it doesn't recognize dcm. Why? It's listed right there in :Mason.

Imo ensure-installed should directly bind to the names of the language servers offered by Mason, it would be 10000x better and make it painless to auto install language server.
