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.

OpenCSD version v0.14.0 adds in a new output element. This is represented
by a new value in the generic element type enum, which must be added to
the handling code in perf cs-etm-decoder to prevent build errors due to
build options on the perf project.
This element is not currently used by the perf decoder.
Perf build feature test updated to require a minimum of 0.14.0
Tested on Linux 5.7-rc3.

The following error was thrown when compiling `tools/perf` using OpenCSD
v0.11.1. This patch fixes said error.
CC util/intel-pt-decoder/intel-pt-log.o
CC util/cs-etm-decoder/cs-etm-decoder.o
util/cs-etm-decoder/cs-etm-decoder.c: In function

cc1: all warnings being treated as errors
Because `OCSD_INSTR_WFI_WFE` case was added only in v0.11.0, the minimum
required OpenCSD library version for this patch is no longer v0.10.0.

This patch adds support for generating instruction samples from trace of
AArch32 programs using the A32 and T32 instruction sets.
T32 has variable 2 or 4 byte instruction size, so the conversion between
addresses and instruction counts requires extra information from the
trace decoder, requiring version 0.10.0 of OpenCSD. A check for the
OpenCSD library version has been added to the feature check for OpenCSD.

The Open CoreSight Decoding Library (openCSD) is a free and open library
to decode traces collected by the CoreSight hardware infrastructure.
This patch adds the required mechanic to recognise the presence of the
openCSD library on a system and set up miscellaneous flags to be used in
the compilation of the trace decoding feature.
