Add support for kernel name filtering to rocprofv2

rocprofv2 does not support the "kernel:" attribute in
input files. This commit adds support for this attribute
for cli/csv output. This is requested by Alibaba/Omniperf
to have compatible execution with both v1/v2 (JSON and CTF
are not supported here and not needed).

Filtering can also be enabled by the flag ROCPROFILER_KERNEL_FILTER.
