Add Intel and Intel Optane Memory attributes/entities

[KucharczykL]

PR creator: Description

Adds attributes/entities for Intel and Intel Optane Memory.

Intel is currently hardcoded in :intel64:/&intel64; and spelled out verbatim (with literal ®/™ characters instead of {thrdmrk}) in the SLES 16.0 and 16.1 release notes. This adds a separate intel attribute and composes the Optane names from it, following the existing vendor/product pattern (amd/amdreg, arm/armreg/cortexreg).

:intel:                      Intel
:intelreg:                   {intel}{thrdmrk}
:optane:                     {intel}{nbsp}Optane
:optanereg:                  {intelreg}{nbsp}Optane{thrdmrk}
:optanemem:                  {optane} Memory
:optanememreg:               {optanereg} Memory

Both entities/generic-attributes.adoc and entities/generic-entities.ent are updated. Rendered output:

attribute	output
{intel}	Intel
{intelreg}	Intel*
{optane}	Intel Optane
{optanereg}	Intel* Optane*
{optanemem}	Intel Optane Memory
{optanememreg}	Intel* Optane* Memory

{nbsp} keeps the vendor and brand together, as in :cortexreg: and :altramax:.

:intel64: is left untouched: it is defined in the PLATFORMS section, above the trademark section where :intel: is defined, so it cannot reference {intel} yet. Could do that separately.

PR creator: In case of entity changes

If you request an entity change: Please check all doc repositories for
occurrences of this entity (including all supported maintenance branches).
If there are any side-effects that come with the entity change you need to fix
those (after this PR has been accepted and rolled out via doc-kit).

• all related fixes in the affected doc repositories and branches are done

This change is purely additive; no existing entity or attribute changes its value, so there are no side effects in downstream repositories. Once this is rolled out, the literal Intel® Optane™ Memory occurrences in the SLES release notes will be switched to {optanememreg}.

PR reviewer: Due diligence

• I have tested the changes in a test repository

In case of entity changes (product names etc.):

• I have checked the changes against our terminology database and found no conflicts
