AX: properties using getOrRetrievePropertyValue are not stored in sparse
property map when empty

rdar://problem/116126895
Reviewed by Tyler Wilcock.
In https://bugs.webkit.org/show_bug.cgi?id=261968 (AX:
AXIsolatedObject::m_propertyMap is not
sparse), all attributes that have a value that is the default for its type are
not stored in the
property map. However, for properties that hit the main thread in
getOrRetrievePropertyValue,
this change means that we will not cache empty values, and could access the
main thread more
frequently as a result of a missing cache entry.
This patch resolves this by always caching the value for properties retrieved
in that method,
regardless of their value.
