rocr: Add support for Mipmapped Array (#1847)

Browse Source 
SWDEV-539526 - Add support for Mipmapped Array in Rocr

Add support for Mipmapped Array functionality in Rocr Runtimeenabling GPU applications to work with multi-level texture mipmaps. The implementation introduces new public APIs for creating, querying, and managing mipmapped arrays across different GPU architectures.
