[mlir][Linalg] Wrong tile size for convolutions fixed

Sizes of tiles (subviews) are bigger by 1 than they should. Let's consider
1D convolution without batches or channels. Furthermore let m iterate over
the output and n over the kernel then input is accessed with m + n. In tiling
subview sizes for convolutions are computed by applying requested tile size
together with kernel size to the above mentioned expression thus let's say
for tile size of 2 the subview size is 2 + size(n), which is bigger by one
than it should since we move kernel only once. The problem behind it is that
range is not turned into closed interval before the composition. This commit
fixes the problem by turning ranges first into closed intervals by substracting
1 and after the composition back to half open by adding 1.
