Previously, none of our `runtime` tests relied on the input coordinate
in any way, so all of the logic was hoisted above the main loop in every
test. This CL adds an artificial reliance on the input coordinate so
that we have at least some SkVM tests with real code in the main loop.
This lets us see debug trace instructions interleaved with real code.
The input coordinate is clamped against a known uniform value
(`colorGreen` always contains 0101) so that the final test output
remains consistent in practice.
Additionally, I noticed that this test was only enabled in ES3, but
it doesn't seem to have anything ES3-specific in it, so it's now
enabled across the board.

This writes an entry to the trace buffer every time a slot value is
changed.

This will be used to populate a trace buffer for the SkSL debugger.
See http://go/sksl-tracing for details and rationale.

Prior to this fix, the new test cases would report that the various loop
terms needed to be constant expressions.

An ES2-compatible for loop supports six separate rel-ops:
< <= > >= != ==
Each rel-op, in addition to its expected usage, is also able to
represent a loop which never terminates, as well as a loop which
terminates instantly. Since SkVM unrolls these loops, we should make
sure we do it properly. We now have unit tests for all of these cases.

All internal usage has migrated to MakeFor..., this removes the old
program kind, and updates some tests.
