 Add ST_Value boundary resample modes

 Add nearest-neighbor boundary resample modes for ST_Value so callers can
 choose upper-left, upper-right, lower-left, or lower-right pixels when a
 point lies on a pixel edge or corner.

 Snap near-integer raster coordinates before applying boundary rounding,
 and reject non-exact resample names instead of accepting prefixes.

 Closes #2116
