Dana Jansensandzygoloid 24bde46181 Change array syntax from [T; N] to array(T, N) (#4981) 
In line with the proposal in #4682, this changes the array syntax to be
array(T, N). `array` is a builtin keyword which must be followed by
parens containing two expressions and a separating comma.

The array type expression is still fully builtin, it does not forward to
a Core.Array library type yet. It merely adds the `ArrayType`
instruction, as was done with the previous syntax.

Followup work will change the instruction to reference to Core.Array,
once the library type exists and can be used directly.
