feat(NODE-6472): run findOne without cursor

[durran]

Description

Changes findOne to set options that will not require a cursor or a killCursors command. Updates find to not leave cursors open on the server when batch size and limit are equal.

What is changing?

• findOne no longer creates a FindCursor object, but instead calls executeOperation with a new FindOneOperation.
• The find one operation now deprecates options for it specifically which are irrelevant.
• The find operation now sets batchSize to batchSize + 1 when the limit it equal to it.
• Syncs CRUD spec tests.

Is there new documentation needed for these changes?

What is the motivation for this change?
