arm64/mpam: resctrl: Export resource's properties to info directory

hulk inclusion
category: feature
feature: ARM MPAM support
bugzilla: 48265
CVE: NA

--------------------------------

Some resource's properities such as closid and rmid are exported like
Intel-RDT in our resctrl design, but there also has two main differences,
one is MB(Memory Bandwidth), for we MB is also divided into two directories
MB and MB_MON to show respective properties about control and monitor type
as same as LxCache, another is we adopt features sysfile under resources'
directories, which indicates the properties of control type of corresponding
resource, for instance MB hardlimit.

e.g.
    > mount -t resctrl resctrl /sys/fs/resctrl -o mbHdl
    > cd /sys/fs/resctrl/ && cat info/MB/features
      mbHdl@1  #indicate MBHDL setting's upper bound is 1
    > cat schemata
      L3:0=7fff;1=7fff;2=7fff;3=7fff
      MB:0=100;1=100;2=100;3=100
      MBHDL:0=1;1=1;2=1;3=1
