[mlir][linalg][nfc] Fix formatting for linalg.elementwise
Follow-up to #124661 to address minor formatting inconsistencies. **Changes:** 1. Standardized test file names by using hyphens (`-`) instead of underscores (`_`). 2. Renamed `"round-trip.mlir"` to `"roundtrip.mlir"` for consistency with similar tests. 3. Normalized indentation. For **(3)**, I ensured we follow the pre-existing formatting style introduced with `linalg.generic`, where all new lines are indented by **8 spaces**. Thus, the formatting is now: ```mlir %r = linalg.elementwise kind=#linalg.elementwise_kind<sub> indexing_maps = [affine_map<(d0, d1) -> (d1, d0)>, affine_map<(d0, d1) -> (d0, d1)>, affine_map<(d0, d1) -> (d0, d1)>] ins(%A, %B: tensor<8x16xf32>, tensor<16x8xf32>) outs(%C: tensor<16x8xf32>) -> tensor<16x8xf32> ``` instead of: ```mlir %r = linalg.elementwise kind=#linalg.elementwise_kind<sub> indexing_maps = [affine_map<(d0, d1) -> (d1, d0)>, affine_map<(d0, d1) -> (d0, d1)>, affine_map<(d0, d1) -> (d0, d1)>] ins(%A, %B: tensor<8x16xf32>, tensor<16x8xf32>) outs(%C: tensor<16x8xf32>) -> tensor<16x8xf32> ``` Submitting this without a review, as these are straightforward changes, and I want to reduce PR traffic/noise. However, please let me know if you prefer changes like these to go through a formal PR review.
