[PATCH 1/4] perf sched: Sync state char array with the kernel

From: Ze Gao
Date: Mon Jan 15 2024 - 02:23:36 EST


Update state char array to match the latest kernel definitions and
remove unused state mapping macros.

Note this is the preparing patch for get rid of the way to parse
process state from raw bitmask value. Instead we are going to
parse it from the recorded tracepoint print format, and this change
marks why we're doing it.
