database/sql: sql.RawBytes is not compatible with contexts [1.20 backport]

[gopherbot]

@rsc requested issue #60304 to be considered for backport to the next 1.20 minor release.

@gopherbot please backport Go 1.20 and Go 1.19

Release planning suggests waiting for the CL to ship in 1.21 RC1 before backporting.

Will also need https://go-review.googlesource.com/c/go/+/498398 it turns out.

Release planning suggests waiting for the CL to ship in 1.21 RC1 before backporting.

The report in issue #60932 looks relevant to the review of this cherry-pick candidate.

[rsc]

There has been enough uncertainty around the database/sql change that, while I think it is appropriate for Go 1.21, I am inclined to not backport it to Go 1.20.

@cherrymui What information do you think this is waiting for? I think given the new information, we can make a decision (not to backport this), like in #60307.

[cherrymui]

I think we decided to give it some time to soak, wait for 1.21 release then decide later (for 1.20 backport only, definitely not enough time for 1.19 backport.)

We've considered the information available by now and have decided not to proceed with this backport. The fix is available in Go 1.21.0 onwards, but the risk of backporting doesn't outweigh the benefits.
