mm/vma: define a default value for VM_DATA_DEFAULT_FLAGS
There are many platforms with exact same value for VM_DATA_DEFAULT_FLAGS
This creates a default value for VM_DATA_DEFAULT_FLAGS in line with the
existing VM_STACK_DEFAULT_FLAGS. While here, also define some more
macros with standard VMA access flag combinations that are used
frequently across many platforms. Apart from simplification, this
reduces code duplication as well.
