Now that unified-shared memory works (with some devices), mark it as 'Y'
and link to the device-specific chapter. While there is always room for
improvement (like having opt-in partial support for managed-memory
semi-USM devices), it works sufficienty for a 'Y'.
Additionally, I saw that 5.2 now extended what is permitted inside
'declare mapper'. Instead of listening the permitted clauses as in 5.1,
it now refers to the 'map' clause such that 'delete'/'release',
'present' and in particular 'iterator' and 'mapper' itself are permitted
inside a declare-mapper 'map' clause. - Thus, I added it as to-do item
to the 5.2 status.
Comments?

PS: As this is also about USM, the declare-target USM issue I mentioned
in several patch emails is now filed as https://gcc.gnu.org/PR115279libgomp.texi: Impl. update for USM and missing 5.2 item
libgomp/ChangeLog:
* libgomp.texi (OpenMP 5.0 status): Mark 'requires' as done and
link to 'Offload-Target Specifics'.
(OpenMP 5.2 status): Add item about additional map-type modifiers
in 'declare mapper'.
