### What changes were proposed in this pull request? revert blockify gmm ### Why are the changes needed? WeichenXu123 and I thought we should use memory size instead of number of rows to blockify instance; then if a buffer's size is large and determined by number of rows, we should discard it. In GMM, we found that the pre-allocated memory maybe too large and should be discarded: ``` transient private lazy val auxiliaryPDFMat = DenseMatrix.zeros(blockSize, numFeatures) ``` We had some offline discuss and thought it is better to revert blockify GMM. ### Does this PR introduce _any_ user-facing change? blockSize added in master branch will be removed ### How was this patch tested? existing testsuites Closes #29782 from zhengruifeng/unblockify_gmm.
