c9e9131f44 Switched SkSL positions from int to Position
This CL switches almost all instances of line tracking over to track
Positions instead. This does not yet add full range support - only the
start offsets will be correct currently. Followup CLs will extend the
ranges to fully cover their nodes.

074a016b89 Remove skstd::string_view entirely.
We now use std::string_view throughout. SkStringView.h has been moved to
include/private/ and is only used for our C++20/23 compatibility methods
(starts_with/ends_with/contains).

df93db9d32 Removed a number of utility methods from DSLWriter
DSLWriter is about to be renamed to something non-DSL-specific, and
(especially since we're in the middle of trying to break up some of our
big classes anyway) it didn't feel right to leave a pile of extremely
DSL-specific utility methods in it. And since it turns out that none of
these methods really do much of anything anymore, it seemed best to
just kill them all.

1a2cef7fbc Avoid returning a DSLExpression with an invalid type.
We shouldn't return expressions that violate basic invariants (such as a
Constructor with an invalid Type) because future code should be able to
rely on those invariants to hold. Returning a Constructor with an
invalid Type broke some assertions I had added; these assertions checked
that the Constructor's type was valid before operating on it.

4a5e22a8c8 Further unified error handling between SkSL and DSL
This eliminates the SkSL ErrorReporter class and funnels everything
through the DSL ErrorHandler. Since the DSL error handler can be
changed, this required a number of updates to ensure that things work
properly in the face of custom error handlers. There is probably more
work to be done in that area, but this at least passes all existing
tests.

dd2fdea9c2 Initial land of DSLParser
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.

a2d22b2e08 Broke DSLVar into separate subclasses
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.

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.
