DefaultLinesDiffComputer did not pass timeout as an option

[CharlesHGong]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: Latest Master

In src/vs/editor/common/diff/defaultLinesDiffComputer/defaultLinesDiffComputer.ts

return this.myersDiffingAlgorithm.compute(
  sequence1,
  sequence2
);

This caller is missing to pass in the timeout variable.

The definition of the myersDiffingAlgorithm.compute looks like this

compute(seq1: ISequence, seq2: ISequence, timeout: ITimeout = InfiniteTimeout.instance)
