Memory API patches
- Directly dispatch MemoryRegion alias accesses
- Remove duplicated Address Space information in 'info mtree'
- Cleanups around memory_region_is_mapped()
- Fix incorrect calls of log_global_start/stop()
- Use dma_addr_t type definition when relevant
- Let dma_buf_read() / dma_buf_write() propagate MemTxResult
- Clarify MemoryRegion aliases documentation
