Currently Linux kernel gathers performance counters at fixed
intervals (~5-10ms), so if application uses AMD_performance_monitor
extension and immediately after glFinish() asks GL driver for HW
performance counter values it might not get any data (values == 0).
Fix this by moving the "read counters from kernel" code from
"is query ready" to "get counter values" callback with a loop around
it. Unfortunately it means that the "read counters from kernel"
code can spin for up to 10ms.
Ideally kernel should gather performance counters whenever we ask
it for counter values, but for now we have deal with what we have.

Otherwise mesa will crash in glEndPerfQueryINTEL because OA BO is NULL.

On Vulkan most of those are already covered by standard queries so
add the ability to skip them.

This stuff is somewhat specific to the GL extension & drivers. On
Vulkan we won't use this, it also made a rather large file.

low-level implementation of INTEL-performance-query APIs in
Intel iris driver. Most of functions and procedures defined here
are adopted from i965 driver (brw_performance_query.c)
v2: - replace genX_init_performance_query with
iris_init_perfquery_functions which is gen's version agnositic
- general code clean-up
v3: include gen_perf_gens.h as some of defines were moved to this new
header file
v4: - checking for kernel 4.13+ won't be needed here as Iris won't be
loaded anyway without DRM_SYNCOBJ that is enabled after Kernel
4.13.
- checking whether gen < 8 or is_cherryview won't be required as
well because those cases are screened in iris_screen_create.
v5: remove genX(init_performance_query)
v6: - remove oa_metrics_kernel_support as iris works only with kernel
4.18 and newer.
- use perf functions defined in separate file, iris_perf.h/c
