Describe every value kind in one table instead of spreading it over the code

A kind like colour or texture used to be spelled out in five parallel
lists, its port type, its empty value, its glyph, its label and its list
tag - 22 literal places for texture alone. core/properties/kinds.ts now
holds one row per kind and the rest is derived from it, so adding a kind
is one row. The five literal nodes collapse into literals.ts, the six
kind menus into one helper.

Number, Text, Boolean is now the one order everywhere; the variable and
port menus used to list Boolean before Text.
