Web Inspector: NMI: switch to hierarchical identifiers of MemoryBlockTypes and use these identifiers in protocol.
https://bugs.webkit.org/show_bug.cgi?id=95957

Reviewed by Yury Semikhatsky.

Source/WebCore:

Now when we use string identifiers as MemoryObjectType we can use them as the identifiers for the protocol
instead of MemoryBlockNames hardcoded in InspectorMemoryAgent..
At a later stage, when each type of memory will be counted in MemoryInstrumentation
we will build the blocks hierarchy for the front-end automatically.
