gccrs: Fix ICE in array ref constexpr
Since 898d55ad7e2 was fixed to remove the VIEW_CONVERT_EXPR from
array expressions we can now turn on the array element access
const expr.
Fixes Rust-GCC#3563
gcc/rust/ChangeLog:
* backend/rust-constexpr.cc (eval_store_expression): turn this back on
gcc/testsuite/ChangeLog:
* rust/compile/issue-3563.rs: New test.
