Fix ReanimatedDrawerLayout animation speed after rerender (#4470)

## Description

Fixes #4469.

`ReanimatedDrawerLayout` memoized `animateDrawer` without
`animationSpeedProp`, so changing the prop did not affect later
programmatic `openDrawer()` or `closeDrawer()` calls. The callback now
tracks the prop and the imperative methods receive the latest default
spring speed after a rerender.
