The layout of the vendor space /misc partition was pretty confusing and lead to some usage conflicts. To formalize the layout, we create a pixel specific library with the definition & offset of various flags. The new library also handles the R/W. As a result, we will leave system domain /misc definitions in the libbootloader_message. We also switch the misc_writer binary to use more specific options instead of writing an arbitrary hex string. So we can avoid redefining the string & offset in both init script and recovery ui. Bug: 131775112 Test: unit tests pass, run misc_writer and check contents of /misc Change-Id: I00f8842a81d1929e31a1de4d5eb09575ffad47c0
