performance: cache MOCS values

Browse Source 
This change caches the most used MOCS values:

* getMOCS(GMM_RESOURCE_USAGE_OCL_BUFFER_CONST);
* getMOCS(GMM_RESOURCE_USAGE_OCL_BUFFER);
* getMOCS(GMM_RESOURCE_USAGE_OCL_BUFFER_CACHELINE_MISALIGNED);
inside gmmHelper class during initialization to avoid repeated
calls of virtual functions, branches and/or gmm lib access.

and adds more readably corresponding getters:
* getL1EnabledMOCS
* getL3EnabledMOCS
* getUncachedMOCS

If force all resources uncached is called,
these 3 cached mocs values are reinitialized

It also changes the order of gmmHelper members, to avoid
not needed padding after addressWidth
and simplifies logic in getMocsIndex function
for xehp and later products.
