Update p4est JLL package to use v2.8.5

[sloede]

p4est v2.8.5 was just released. It would be great if we could update the Yggdrasil recipe (and subsequently the JLL package) to use that version as well.

Note: the release tarball is named p4est-2.8.5.5-9ddbb.tar.gz on https://github.com/p4est/p4est.github.io/tree/master/release/, but I think this is still considered to be "p4est v2.8.5" (please correct me if I am wrong, @cburstedde).

Cool! Please note that P4EST_QMAXLEVEL is valid for all quadrant operations except for set_morton and linear_id, for which P4EST_OLD_QMAXLEVEL is the limit. We have added 128 bit alternatives of the latter. The question becomes, shall the linear index type be generally promoted to 128 bit, or shall we reduce the level for set_morton and linear_id?

Thanks for the heads up!

Let's wait until the issue with the .la files is sorted out before updating the JLL package.
