org-persist: Allow inhibiting of normalisation 

* lisp/org-persist.el (org-persist-register,
org-persist--normalize-container,
org-persist--inhibit-container-normalization): Since container
normalisation is applied frequently (via
`org-persist--normalize-container'), when registering many new
containers the cost can quickly add up.  To avoid redundant overhead,
after normalising the container initially in `org-persist-register' we
bind a new variable `org-persist--inhibit-container-normalization' to t
and adjust `org-persist--normalize-container' to do nothing when this
new variable is non-nil.
