perf: Add PERF_RECORD_MISC_MMAP_DATA to RECORD_MMAP Type of mapping was lost and made it hard for a tool to distinguish code vs. data mmaps. Perf has the ability to distinguish the two. Use a bit in the header->misc bitmask to keep track of the mmap type. If PERF_RECORD_MISC_MMAP_DATA is set then the mapping is not executable (!VM_EXEC). If not set, then the mapping is executable.
