colexec: add optimized support of "contains" LIKE match

[clucle]

Previously, Like matching has "prefix" match(test%) and "suffix" match(%test).

This commit adds "contains" match (%test%) using bytest.Contains function.

Release note (sql change): Add support for "contains" match(%test%) using bytes.Contains function

This will fail - colBatchScan has just been exported., so we need to keep colfetcher.ColBatchScan.

@yuzefovich

Do I need to rebase upstream/master and push again?

[yuzefovich]

No need, our merging bot has been mysteriously crashing.
