Subject: [PATCH] Fix build with GCC 11

It seems redundant to array_init() when the structure is zeroed already
in the static assignment. But probably the fact that this code juggles
between TSTreeCursor and TreeCursor, without using a union, leaves the
compiler unable to tell that it's been initialized.

Fixes https://github.com/tree-sitter/tree-sitter/issues/853
