SkRuntimeEffect needs an API for generating debug traces. This means
that we will need references to debug traces inside a public header.
Rather than reference SkVMDebugInfo directly, we now have a simpler
base class for debug traces. This is better suited to landing in
include/.
I've also renamed SkVMDebugInfo to SkVMDebugTrace for consistency, since
it now contains all the trace data. (When it was first added, it only
had the slot info.)

I ran into a snag while trying to hook up SkRuntimeEffect with debug
tracing. Runtime effects only have access to a skvm::Builder, and are
never exposed to the full skvm::Program. SkVMBlitter is responsible for
assembling the full skvm::Program, but is oblivious to runtime effects
and nested skvm sub-programs. Additionally, multiple runtime effects can
(and often do) coexist within a paint.
This CL changes how debug traces are enabled. skvm::Program no longer
has a `attachDebugTrace` method. Instead, this method lives on the
skvm::Builder. Calling `attachDebugTrace` generates a "trace-hook ID"
(which is actually an index into a vector of TraceHook pointers).
Every trace opcode now includes this trace hook ID. When the Builder
assembles a final Program, it copies the TraceHooks into the Program.
The skvm interpreter uses the trace hook ID on the op to dispatch a
trace command to its associated TraceHook.
From a user perspective, this doesn't change very much, but it does
mean that the SkVM Code Generator now supplies a TraceHook for us
(since it adds trace ops to the Builder and needs to know the proper
trace-hook ID).

This shouldn't change code generation when debug traces are disabled.
When they are enabled, we now get trace_var opcodes emitted for every
return statement. Internally, this required a fair amount of refactoring
around how return values are passed around, but it should all be
functionally equivalent.

SkRuntimeEffect users will be insulated from skvm and the Builder, so
they won't be able to make an skvm::Coord directly. Replace this with

This also removes the requirement of assigning a trace coordinate; if

Previously, we would avoid emitting redundant trace_vars by checking to
see if the slot is being assigned to the exact same Var.ID. However,
this had the potential to eliminate useful trace_vars:
- At the start of execution, slots all contain 0. Code which explicitly
assigned a zero into a slot would not be shown in a trace. (So things
like `color = half4(0,1,0,1)` would only emit traces for color.ga.)
- A function call's parameter slots are reused every time it is called,
so calling a function twice would only emit traces for the parameters
that aren't the same Val.ID as the previous call.
- A VarDeclaration inside a loop reuses its slot each time through the
loop, even though conceptually it's a "new" variable.
We now track a slot's "written-to" status. At the start of execution,
no slots have been "written-to". These slots will always emit a
trace_var opcode (fixing the first issue). Also, issuing a function
call or declaring a variable will reset the "written-to" status of the
associated slots (fixing the second and third issues).
When the debugger is not in use, the written-to field is unused.

When calling ProgramToSkVM, you can now pass in a pointer to an
SkVMDebugInfo struct. Passing in this pointer now enables trace opcodes,
removing the need for a dedicated `fSkVMDebugTrace` flag.
In this CL, the struct is empty, but in followup CLs it will contain
mapping tables that can be used to translate trace instructions into
human-readable results (e.g. slot numbers to variable names).

Evaluating either kind of expression now works like all other
expressions - evaluate the inner part, then work with the resulting
values. Added unit tests for both of these that previously failed.
With this change, writeVariableExpression is only used for
VariableReference expressions, so adjust that, too.

This enforces an even stricter version of the rules from GLSL ES 1.0
Appendix A, Section 5. Essentially, indices (to arrays, vectors,

This was disabled a long time ago, when this was (incorrectly) forbidden
by the IR generator, most likely.

These need to change because type coercion in SkSL is about to become
more strict in a followup CL; we are disallowing expressions that mix
ints and floats without a cast.

Previously, these were in SkSL::Context directly. This change doesn't
remove them from the context entirely, but it gives them a dedicated
subclass and firewalls them off from the rest of the context.
