electron19: fix build
#### Testing the changes
- I tested the changes in this PR: **NO** (but yes? because it's for the build)

#### Local build testing
- I built this PR locally for my native architecture, **x86_64**


#### Comments

While checking ffmpeg5/6 changes I was having trouble building `electron19`. There have been a few big changes lately and the last build fix was months ago, so I'm not sure what changed. (Looks like a lot of active patching or something in the template?)

Going to verify non-ffmpeg change build tonight if I remember.

+Subject: [PATCH] sql: relax constraints on VirtualCursor layout
+
+VirtualCursor::FromSqliteCursor required that VirtualCursor had a
+standard layout, but in fact VirtualCursor shouldn't have a standard
+layout, and the fact that it does with libc++ is a deviation from the
+C++ standard. This change:
+
+1. Relaxes the requirement that VirtualCursor has a standard layout, and
+2. Relaxes the requirement that the sqlite_cursor_ field has to be at
+   offset 0
+
+by use of offsetof() and pointer subtraction. This change both improves
+standards compliance and makes this code build with libstdc++.
