perf cs-etm: Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0

Replace the OCSD_INSTR switch statement with an if to fix compilation
error about unhandled values and avoid this issue again in the future.

Add new OCSD_GEN_TRC_ELEM_SYNC_MARKER and OCSD_GEN_TRC_ELEM_MEMTRANS
enum values to fix unhandled value compilation error. Currently they are
ignored.

Increase the minimum version number to v1.0.0 now that new enum values
are used that are only present in this version.
