Update the PMIx package (#10442)

* Update the PMIx package

- Add latest releases to the list.
- Add dependency on hwloc for versions >= 3.0
- Flag preferred versions for libevent and hwloc
- Improve the description
- Point the project URL to the correct site

Signed-off-by: Ralph Castain <rhc@pmix.org>

* Only install the hwloc dependency for versions >= 3.0.0

Thanks to @ax3l for the suggestion

 class Pmix(AutotoolsPackage):
-    """The Process Management Interface (PMI) has been used for quite some time
-       as a means of exchanging wireup information needed for interprocess
-       communication. Two versions (PMI-1 and PMI-2) have been released as part
-       of the MPICH effort. While PMI-2 demonstrates better scaling properties
-       than its PMI-1 predecessor, attaining rapid launch and wireup of the
-       roughly 1M processes executing across 100k nodes expected for exascale
-       operations remains challenging.  PMI Exascale (PMIx) represents an
-        attempt to resolve these questions by providing an extended version
-       of the PMI definitions specifically designed to support clusters up
-       to and including exascale sizes.  The overall objective of the project
-       is not to branch the existing definitions - in fact, PMIx fully
-       supports both of the existing PMI-1 and PMI-2 APIs - but rather to
-       (a) augment and extend those APIs to eliminate some current restrictions
-       that impact scalability, (b) establish a standards-like body for
-       maintaining the definitions, and (c) provide a reference implementation
-       of the PMIx standard that demonstrates the desired level of
-       scalability."""
