Zero the workgroup memory for all backends.
We can probably disable this for the backends that support workgroup zeroing, but that's an optimization we can perform later.

When moving private and workgroup variables into the entry point,
generate pointers to pass as arguments to sub-functions on demand,
instead of upfront. This removes a bunch of unnecessary dereferences
for accesses inside the entry point, and one function variable.

Add a transform that pushes these into the entry point and then passes
them by pointer to any functions that need them.
Since WGSL does not allow non-function storage class at
function-scope, add a DisableValidation attribute to bypass this
check.

Adds additional modes to the Renamer for renaming just HLSL or MSL
keywords. The sanitizers no longer rename reserved keywords
automatically, which isn't usually necessary anyway since Dawn renames
all symbols.
The tint executable automatically renames reserved keywords when
targeting HLSL and MSL. It now also has an option to rename
everything, which is useful for testing the renamer.

SymbolTable::New() used to build and return a symbol without a registered name. When you asked for the name of the symbol it would return tint_symbol_N, where N is the numerical identifier for the symbol.
This approach was a major tripping hazzard for transforms that liked to fetch the source program name, and register it in the new program (in this situation, you should always use `CloneContext::Clone(Symbol)`).
Without special casing for unnamed symbols, you could end up promoting the unnamed symbol to a named symbol, and then colliding against a new unnamed symbol.
This is exactly what happened in tint:711.
Instead, with this change:
* The concept of unnamed symbols has been removed. All symbols now have a name.
* The signature of `SymbolTable::New()` has been changed to take a name parameter (which defaults to 'tint_symbol'). This can be used to create a new, unique named symbol (possibly with a suffix), which will not collide with any existing symbols. Note these symbols may still collide if `SymbolTable::Register()` is called with the same name. All Transforms that currently use `SymbolTable::Register()` will be fixed in another change.
* The CloneContext has been updated to use `SymbolTable::New()` instead of `Register()`. This means that any symbols defined before a clone will not collide.
* `CloneContext::CloneSymbols()` has been added which allows a transform to pre-clone all the symbols from the source program. This can be used to avoid the authored identifiers being suffixed with a number, in the case a transform calls New() before the symbol is cloned.
* `Symbol::to_str()` has been changed to return `$<id>` instead of `tint_symbol_N`. This is to avoid any confusion between the actual name and the symbol ID.

All includes from .cc to .h are preserved, even when transitively included.
It's clear that there are far too many includes in header files, and we should be more aggressive with forward declarations. tint:532 will continue to track this work.
There are, however, plenty of includes that have accumulated over time which are no longer required directly or transitively, so this change starts with a clean slate of *required* includes.

This change begins the work to move the reserved keyword remapping out of the writer and into the sanitizer transform.
If the transform::Renamer is in use, then these symbols should never have to be remapped - however for debugging purposes it is often nice to be able to emit code that isn't entirely mangled.
The logic in the msl writer will be removed as a followup change
