init-debug.rc: don't mount debugfs

Motivation:
1. Reduce skew between userdebug and user builds.
2. Make the decision to mount debugfs on debug builds on a
   per-device basis.
3. Prepare to not mount it at all to reduce the attack surface
   of the kernel, reduce boot time, and free up memory.
4. Remove the selinux denial on devices that mount twice, i.e.
   unconditionally in the device specific .rc file and in the
   init-debug.rc file.
   avc: denied { mounton } for path="/sys/kernel/debug" dev="debugfs"
   ino=1 scontext=u:r:init:s0 tcontext=u:object_r:debugfs:s0
   tclass=dir permissive=0

If desired, debugfs may be mounted in device specific rc files
instead.

Test: Build and boot Marlin. Selinux denial no longer observed.

init-debug.rc: add runtime mmc max speed property actors

persist.mmc.max_read_speed  - KB/s speed cap
persist.mmc.max_write_speed - KB/s speed cap
persist.mmc.cache_size      - MB of high-speed on-device write cache

device default directly to associated /sys/block/mmcblk0/ attributes,
not delivered on "user" builds.
