LibJS: Remove inline capacity from MarkedVector

Browse source 
Turns out this was hurting performance instead of helping it.
By removing the inline capacity, we shrink the size of ExecutionContext
by 512 bytes, which substantially reduces the stack pressure created by
JS recursion (each call creates a new ExecutionContext on the stack).

4.4% speed-up on the entire Kraken benchmark :^)
