GPKG: incorrect matrix_width / matrix_height

Description (last modified by Even Rouault)

Requirement 45 

The width of a tile matrix (the difference between min_x and max_x in gpkg_tile_matrix_set) SHALL equal the product of matrix_width, tile_width, and pixel_x_size for that zoom level. Similarly, height of a tile matrix (the difference between min_y and max_y in gpkg_tile_matrix_set) SHALL equal the product of matrix_height, tile_height, and pixel_y_size for that zoom level.

But currently our matrix_width / matrix_height is adjusted in a much tigher way.
