feat(soba/misc): injectDepthBuffer returns DepthTexture instead of Signal

Due to change to `injectFBO`, `injectDepthBuffer` no longer returns a
`Signal` (because there is no need to)

BREAKING CHANGE: `injectDepthBuffer` returns `DepthTexture | null`
instead of `Signal<DepthTexture | null>`. Consumers should update
accordingly
