Implement promote_to_multi when converting WKB to sfc

[paleolimbot]

Apologies for taking so long to circle back here, but this is one approach to ensuring that R CMD check passes when R_SF_ST_READ_USE_STREAM=true. It also has the nice side-effect that use_stream = TRUE no longer uses the wk package to construct sfc objects and that all users of st_as_sfc(<WKB>) can now use promote_to_multi = TRUE to get the same read-ogr-like behaviour.

Closes #2296.

Example:

library(sf)

vec <- st_sfc(
    st_point(c(0, 1)),
    st_point(),
    st_point(c(2, 3)),
    st_multipoint(matrix(c(4, 5), ncol = 2))
)

wkb_vec <- st_as_binary(vec)

st_as_sfc(wkb_vec, promote_to_multi = FALSE)
st_as_sfc(wkb_vec, promote_to_multi = TRUE)

I do still see:

Failure (test-tm.R:20:3): st_read and write handle date and time
x[["tm"]] not equal to x2[["tm"]].
Attributes: < Component “tzone”: 1 string mismatch >

Failure (test-tm.R:40:3): st_read and write handle date and time
x[["tm"]] not equal to x2[["tm"]].
Attributes: < Component “tzone”: 1 string mismatch >

...when running testthat::test_local() with R_SF_ST_READ_USE_STREAM=true. I think this happens because of how nanoarrow converts timestamps without an explicit timezone to R objects: nanoarrow assigns UTC as opposed to setting tzone = "" or omitting it. I copied this behaviour from readr because it is more reproducible between systems, but I'm not sure it's any more or less correct.

There are still several tests failing for me on this PR:

[paleolimbot]

There are still several tests failing for me on this PR:

I'll revisit in a bit! These are failing tests when specifically using the GDAL stream API, correct? If so, I think it is because nanoarrow implements "timezonelsss" timestamp conversion to R as assigning the UTC timestamp (for portability between the same code running on two computers...readr does this too). I may be remembering the details incorrectly!

(I'm not sure about the CRS test case!)
