Disable location stats calculation for big images (Fixes #11420)

Ticket for reference with more overarching explanation:
* https://trac.openmicroscopy.org.uk/ome/ticket/11420

Testing requirements:

1. Read-Annotate or Read-Write group (at least two users present in the group)
2. 8 bits per channel RGB image (Aperio SVS suggested)
3. 16 bits per channel image (Aperio AFI suggested)

Expectations before (8 bits per channel):

1. As the user who imported the image thumbnail display should be available in a few seconds
   * The scale for all three channels should be `[0, 255]`
2. As *another* user who has permissions to see the image the thumbnail display should be available in a few seconds
   * The scale for all three channels should be `[0, 255]`

Expectations after (8 bits per channel):
* Identical to those before

Expectations before (16 bits per channel):

1. As the user who imported the image thumbnail display should be available in a few seconds
   * The scale for all three channels should be some calculated values in the range `0-65535`
2. As **another** user who has permissions to see the image the thumbnail display should be take many minutes, timeout, cause the server to crash or completely not display
