provider: repurpose E319

Browse Source 
In Vim (and some vestigial parts of Nvim) E319 was a placeholder for
ex_ni commands, i.e. commands that are only available in certain builds
of Vim.  That is obviously counter to Nvim's goals: all Nvim commands
are available on all platforms and build types (the remaining ex_ni
commands are actually just missing providers).

We need an error id for "missing provider", so it makes sense to use
E319 for that purpose.

You have used a command that is not present in the version of Vim you are
using. When compiling Vim, many different features can be enabled or
disabled. This depends on how big Vim has chosen to be and the operating
system. See |+feature-list| for when which feature is available. The
|:version| command shows which feature Vim was compiled with.
