sql: allow implicit casting of string to more array types

[rafiss]

Release note (sql change): A string literal like '{X, Y, Z}'
is now automatically casted to an array when appropriate. Support is
added for UUID, Date, Bool, Time, TimeTZ, Timestamp, TimestampTZ, and
Interval arrays. (Int and Decimal were already supported.)

fixes #54672

Should we add some logic tests as part of this change? I see there's an array logic test file, which may be a good place?

Change looks good to me, though it would be nice to get a quick look from @otan as well as he's way more familiar with this stuff.

Reviewable status: complete! 0 of 0 LGTMs obtained (waiting on @aadityasondhi, @arulajmani, and @solongordon)

[rafiss]

added the logic test. @otan would you like to look at this? no need to if you're busy, i feel comfortable going ahead as is.

[otan]

seems fine to me, curious why we can't do the others

[rafiss]

ah you mean arrays of other types? we could -- i was just being lazy and sort of deferring to the types that were already tested in constant_test.go.

well technically, we don't support json[] but i can do the other ones and add them to that test.

[otan]

happy for that to be a separate PR. just wondering where the line stops :P

[rafiss]

It was easy enough to add FloatArray, INetArray, and VarbitArray to this PR.

unfortunately I had trouble with Box2d, Geometry, and Geography arrays, so not including them here.

[rafiss]

TFTRs! i'm merging, and will backport to 20.2 after the initial 20.2.0 release goes out
