(get_cached_data): Force chace use if flag is set.
(app_select_openpgp): Avoid reading DO 6E multiple times.

The do not cache property of 6E was introduced so that we can change
for example key attributes without getting into with the cache.
However, for initial reading the cache makes a lot of sense and thus we
now use this hack to only temporary cache.  A better strategy would be
to clear the cache when we change card data but that is more error
prone.

scd:piv: Improve APT parser compatibility.
* scd/app-piv.c (app_select_piv): Allow for full AID.
--

It appears that SP-800-73-x is not too clear about the format of these
objects. Many current cards (such as the Yubikey 5 series) apparently
have only the PIX in DO 0x4F and only the RID in object 0x79/0x4F.

However, other cards as well as the PivApplet Javacard applet have the
full AID in 0x4F (which actually seems closer to what the standard
says). PivApplet also has the full AID in 0x79/0x4F, but this is
probably incorrect. (Here is a long discussion of the matter from an
OpenSC author:
https://github.com/arekinath/PivApplet/issues/43#issuecomment-772649709)

This features allows to mark keys to be used for OpenPGP.  This is

for a stored certificate this new mode chimes in.
