We were writing descriptors into si_context and then copying them into
the command buffer. Just write them into the command buffer directly.
Also set the pointer to VBO descriptors right after them.
When we start a new command buffer or we finish blitting, we no longer
restore precomputed VBO descriptors. Instead, we just reupload them again.
It's a compromise to have the common path simpler and faster (maybe).
This removes a lot of stuff. Now the VBO descriptor upload path looks
very similar to the display list path.
There was an accidental hidden optimization that is now documented as
"last_const_upload_buffer".

We can't invalidate CCU if there is any dirty data that hasn't been
flushed yet. In the case where we clear depth, we know that the depth
attachment itself isn't dirty but there may be dirty data from other
renderpasses. Therefore we need to flush before invalidating depth.

- $GPU_VERSION_unittests-$MODE.txt
Where:
- $MODES can be crashes, fails, and flakes
- $SKQP_BACKEND can be gl, gles and vk
crashes and flakes removes tests from skqp, so they will not be run.

When the skqp is introduced to a new driver, the best practice is to
run all available tests from skqp and classifying the
failing/crashing/flaking ones.
The default behavior of skqp is to run the tests from the commit where
the skqp built, which may not be adequate for the target driver.

This reverts commit 96fa23bca5.
The correct fix to the problem was a1bc152340, making this
change obsolete as the pass skips any vars marked with
always_active_io. There was no real advantage to allowing these
vars to be split because they can't be removed anyway. Also there
is no way to split varying arrays gracefully here due to the xfb
layout rules, and this change didn't handle arrays at all.
Removing this obsolete code also fixes an assert in the new CTS
test KHR-Single-GL45.enhanced_layouts.xfb_all_stages. The test
was legally adding xfb offsets to all vertex stages but since
we only mark the varyings in the final vertex stage with the
always_active_io flag the other stages were correctly lowering
to scalars but when an array with an offset hit this code it
asserted since it couldn't handle it.

dEQP-GLES2.functional.shaders.operator.binary_operator.div.highp_int_fragment.
I'm happy to eat that cost in exchange for correct results!
There are lots more low-hanging opportunities for optimizations to that
shader:
- fuse double icmpsel for the b2i32(cmp) sequences
- promoting big immediates to uniforms
- fusing integer multiply+add
But for now this is acceptable and anyway I'm doing this on "fix broken
