Name the column of any table, and keep Column checked

[johanrd]

On top of universal-ember#202 (60dafd9). An alternative to the CellArgs = any default in that commit, and to #4.

60dafd9 makes CellArgs default to any so that a column whose Cell asks for args fits a Column<DataType> parameter — which the plugin helpers need. It also makes the Cell of every column written by hand unchecked:

// 4.0.0:   ComponentLike<CellContext<Person>>   — @row and @column required
// 60dafd9: ComponentLike<any>                   — any args, none required
type Cell = Column<Person>['Cell'];

So <column.Cell /> with no args, or with args no Cell takes, now passes at any site that writes Column<T> by hand.

The two readings of Column<Person> cannot both hold: "a column I will render", which needs the Cell checked, and "a column I only read", which needs any column to fit. This gives the second one its own name.

• AnyColumn and AnyTable are what the plugin helpers, meta.forColumn, the header modifier and the resize handle take.
• CellArgs goes back to unknown, so Column<Person> is checked again.
• Your takesAnyColumn and takesAnyTable in cell-args.test.ts say AnyColumn / AnyTable, and still pass.

88 lines of source across 11 files, against 250 in #4, which threaded the four parameters through every plugin signature instead. #4 can be closed either way.

Checked: the package, its type tests and test-app are clean. Our app — 13 tables, about 300 call sites — type checks and lints clean on this plus #6.
