general: Use std's OnceCell where possible

Rust's standard library now provides a drop-in replacement
for `OnceCell`. It requires no API changes from `once_cell`'s
version.

This commit replaces the version from `once_cell` with the
new `std` struct where possible. We still need to use
`once_cell` for properties until
https://github.com/gtk-rs/gtk-rs-core/pull/1113
is merged. We also still need it for Lazy until that lands.
