Support LuaJIT's `table.new` and `table.clear`

[liquidev]

These are (as far as I know) undocumented functions that LuaJIT provides after you require "table.new" and require "table.clear" respectively.

table.new is a binding to lua_createtable, which allows you to preallocate a table with a specified amount of elements in the array part and the record part. The signature is as follows:

function table.new(narr: number, nrec: number): table

table.clear is a binding to lj_tab_clear, which clears a table without having to iterate over all of its elements. Its signature is as follows:

function table.clear(t: table)

Right now if you try to use either of them, the language server complains that they don't exist:

Just an FYI: there are annotations for these in the OpenResty library, so if they are to be added to LuaJIT proper at the runtime level they will be redundant and should get removed:

Hi @liquidev, is the issue resolved for you?

As far as I can tell this should work fine. Thanks a lot!
