lib: optimize copyError with ObjectAssign in primordials

optimized the copyError function by using ObjectAssign from primordials.
this change replaces the for-loop with ObjectAssign, which improves
memory usage and performance.

this change updates the copyError function in internal/assert.js to
use ObjectAssign for copying properties.
