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

This is another strange, experimental feature that clutters the
implementation and isn't used by anyone (to my knowledge).

These enforce stricter rules about the signature of main, and each one
uses a separate pre-include module. That prevents color filters from
being able to reference sk_FragCoord (or coords passed to main) at all.
It also limits the versions of sample() that are exposed.
In the new world, an effect created for a specific stage of the Skia
pipeline can only be used to create instances of that stage (SkShader or
SkColorFilter). For now, SkRuntimeEffect::Make uses kRuntimeEffect,
which continues to be more lenient and allow creation of either shaders
or color filters from a single effect. After we migrate all clients, we
can deprecate and then delete that mode.

Also adds tests of non-uniform shader declarations. These are currently
allowed, but will be detected as an error in the next CL.

This adds Analysis::IsConstantExpression, to determine if an expression
is a constant-expression. It now expands to cover 'const' local and
global variables, because we also enforce that the initializer on those
variables is - in turn - a constant expression.
This fixes 10837 - previously you could initialize a const variable with
a non-constant expression, and we'd emit GLSL that contained that same
pattern, which would fail to compile at the driver level. That should
not be possible any longer.

None of these are legal in GLSL ES 1.0. Added a new test that previously
compiled without error. Started out with just assignment and equality,
then realized that sequence and ternary should be blocked, too.

This is enforced by ANGLE in Strict ES2 mode; we need to enforce it as
