We were previously using a mix of pass-by-value and pass-by-pointer (to
allow for explicitly null PositionInfo). Being able to pass a null
PositionInfo didn't really add much, since we can just use a nullary-
constructor PositionInfo instead, so these have all been migrated to
by-value.

It's still accessible internally (and by default when using
SkMakeRuntimeEffect), but we don't want clients using this.
If we can come up with a simple and consistent coordinate
model that doesn't expose implementation details, we'll
revisit this.

The DSLParser is an alternative to the existing SkSLParser which goes
directly to IR code using the SkSL DSL. It is substantially faster and
simpler than the existing parser->IRGenerator pipeline, but not yet
feature complete nor fully tested.

Previously, DSLVar represented local, global, and parameter variables.
This splits it into three separate subclasses.
In addition to just being a cleaner API in general, this also addresses
an issue we ran into with the upcoming DSLParser: previously, a global
DSLVar's storage was not set correctly until DeclareGlobal was called,
so an AddToSymbolTable call prior to DeclareGlobal would create the
SkSL variable with the wrong storage, causing spurious errors on
global-only modifiers. But holding off on the AddToSymbolTable tends to
break constructs like "int x = 0, y = x", so improving the API seemed
like the best way to address it.
Now that we have greater type safety around variables, we can
potentially avoid having to call AddToSymbolTable for DSLVar and
DSLGlobalVar altogether, since we know they are both supposed to end up
in the symbol table, but that isn't something I want to change in this
CL.

This breaks up the giant IRGenerator::convertFunction method into more-
manageable chunks, moves the functionality into FunctionDeclaration,
and funnels the DSL through it so it receives the same error checking.

This adds an explicit DeclareGlobal call, which must now be called for
variables that were previously implicitly global.
