chore: Pass error call to vec_as_location()

[lionel-]

Part of #1065.

This is just a POC for how to better support error calls in tibble. In this case I'm just passing the relevant call = caller_env() down to vctrs functions. You can also pass it to abort(), or you can assign cnd$call <- <caller_env> before calling cnd_signal().

Note that input checking functions that check a particular argument should also pass arg to abort(). The last version of rlang now highlights the corresponding argument in the backtrace. The function call is also highlighted, provided a frame environment was supplied as call.

Can you please merge the main branch? I can do it but want to avoid collisions because this seems active now.

[krlmlr]

Let's wait for #1239.

Done now.

Thanks, this looks so much better now! I'll go through all internal calls to abort() to incorporate this pattern for the CRAN release after next.

Thanks!
