6ac5310dfa Incorporate top-level DSL blocks into fragment processors.
A Block() at the top-level scope would previously disappear silently.

debcbbf6a8 Flip the arguments to sample() when passing both coords and a color
A subset of these signatures will be available to public SkSL, and
structured in a way that really pushes the coords as the primary
argument (and color as an optional one). In any case, I find this
ordering more natural.

80f6235688 Fixed an issue with passing DSLVar as a DSL function parameter
DSLVar is normally implicitly converted to DSLExpression wherever it is
used, but the naively template-ized nature of DSLFunction::operator()
meant that it was accepting DSLVar parameters directly. Since DSLVar is
non-copyable, this meant DSLVar couldn't be passed directly to a DSL
function.

The smarter templates in this change are able to pass DSLVar by
reference.

b14e6b9055 Added _Type suffix to DSL Type enum
No functionality changes, just making the naming consistent with our
other enums.

707d31578c Refactored DSL variable creation
Prior to this change, we were creating the SkSL variable and declaration
immediately on DSLVar creation. This causes problems with function
parameters, which are sometimes supposed to be tagged
SK_MAIN_COORDS_BUILTIN. If we have already created the variable and
inserted it into the symbol table, then by the time we determine the
variable is supposed to be SK_MAIN_COORDS_BUILTIN, it is too late to
modify the (now-const) variable.

We are not yet doing this tagging, but refactoring the creation in this
fashion paves the way to making it possible.

24c1772ea4 Fixed an issue with DSL includes
It turned out that everywhere we were using or testing DSL code either
directly or indirectly imported big chunks of the SkSL library. These
imports turned out to be necessary; code written using just DSL.h would
fail with various template instantiation errors.

fe5d6928d0 DSL var values are now specified at construction time rather than in
Declare

This solves several issues caused by the lack of ordering guarantees in
C++; it was possible for the SkSL backend to look for the value of a
variable before its Declare() call gets processed. Moving the initial
value out of Declare should fix this whole class of problems.

daed2592bb Made SkSL DSL into public API
In addition to the unsurprising changes to eliminate references to
src/, we also had to tighten up some C++17-isms as they are not
permitted in public headers.
