feat(r): Support native creation of more numeric Arrow arrays from integer vectors

[paleolimbot]

Before we had been punting to the arrow R package for this which wasn't necessary! This was exposed by a test that had been added for matrix support that wasn't skipped if arrow wasn't installed.

library(nanoarrow)
as_nanoarrow_array(1:10, schema = na_double())
#> <nanoarrow_array double[10]>
#>  $ length    : int 10
#>  $ null_count: int 0
#>  $ offset    : int 0
#>  $ buffers   :List of 2
#>   ..$ :<nanoarrow_buffer validity<bool>[null] ``
#>   ..$ :<nanoarrow_buffer data<double>[10][80 b]> `1 2 3 4 5 6 7 8 9 10`
#>  $ dictionary: NULL
#>  $ children  : list()
