Changes:

• Enabled ets:insert/2 to accept lists for bulk insertion.
• Extracted helper functions for ets:lookup/2 and ets:insert/2 that do not apply table locks.

Use Cases for the Helper Functions:

The new helper functions can be utilized in the following ETS operations to reduce code duplication:

• ets:update_element/3
• ets:insert_new/2
• ets:update_counter/3
• ets:update_counter/4
• ets:take/2
• ets:delete_object/2

Every mentioned function will be implemented after merging of this PR.

We usually don't do VM abort: calling AVM_ABORT() means that an unrecoverable happened, such as memory corruption, a bad internal bug and any other kind of situation that required an entire VM crash and reboot.
Are we in this specific situation?

Now we don't have any other tool to ensure atomicity here. In case the insert fails at the Nth element, elements (0,N -1) will be inserted into the list, which could result in hard-to-debug behavior. It is unlikely to happen.
