Override delete for GrOp

We are seeing a crash in a flutter desktop linux application with the
the issue pointing to a sized delete mismatch:

debugallocation.cc:788] RAW: delete size mismatch: passed size 160 !=
requested / available size 192 / 192

This patch fixes the issue. The crash started after the roll that
brought in https://skia-review.googlesource.com/c/skia/+/382701
