intel/perf: move the perf context into perf

The "context" that is necessary to submit and process perf commands to
the hardware was previously present in the brw_context.perfquery
struct.  This commit moves it into perf and provides a more
understandable name.

The intention is for this struct to be private, when all methods that
access it are migrated into perf.

implemented in perf, the struct needs to be defined there.

Performance metrics collections requires several actions (eg bo_map())

There's no reason to bring format-less load requirement into this

computed from the size + data type. For example

becomes

  DCL IMAGE[0], 1D, PIPE_FORMAT_R32_SINT, WR

whereas PIPE_CAP_IMAGE_LOAD_FORMATTED is designed to allow
PIPE_FORMAT_NONE to be provided as a format and still enable LOAD
operations to be performed.

So the shader has all the information it needs about the format.
