The MSL writer GTest harness (TestHelper) now provides a function to
invoke the XCode SDK Metal compiler for the MSL output of a given
tint::Program.
The tint_unittests binary now provides the `--validate-msl` and
`--xcrun-path` command-line flags to optionally enable MSL validation
and to configure its path.
The MSL validation logic itself is conditionally compiled based on the
TINT_BUILD_MSL_WRITER define. The TINT_BUILD_* flags were previously
not propagated to the GTest binary which this CL addresses by linking
the common/public tint configs when building the tint_unittests_main
target.

Registering a new Symbol with the NameFor() of the source symbol creates
a new *named* symbol. When mixing these with unnamed symbols we can have
collisions.
Update CloneContext::Clone(Symbol) to properly clone unnamed symbols.
Update (most) the transforms to ctx.Clone() the symbols instead of
registering the names directly.
Fix up the tests where the symbol IDs have changed.
Note: We can still have symbol collisions if a program is authored with
identifiers like 'tint_symbol_3'. This will be fixed up in a later
change.

Checks the following things:
- Non-struct entry point parameters must have pipeline IO attributes
- Non-struct entry point return type must have a pipeline IO attribute
- Structs used as entry point parameters and return values much have
pipeline IO attributes on every member
- Structs used as entry point parameters and return values cannot have
runtime array or nested struct members
- Multiple pipeline IO attributes on a parameter, return type, or
struct member is not allowed
- Any given builtin and location attribute can only appear once for
the return type, and across all parameters
Removed tests for nested structs from the SPIR-V transform/backend.
Fixed a couple of other tests with missing pipeline IO attributes.

After the transform, an entry point's parameters will be aggregated
into a single struct, and its return type will either be a struct or
void. All structs in the module that have entry point IO decorations
will have exactly one pipeline stage usage.
This will be used to sanitize entry points for the MSL and HLSL
generators.

There is still no way to spell this out in WGSL, but this adds support
for VariableDecls with an ast::Variable that has nullptr type. In this
case, the Resolver uses the type of the rhs (constructor expression),
which is stored in semantic::Variable.
Added tests for resolving inferred types from constructor, arithmetic,

* Formerly, we reported the same error message if we detected no default
clause or more than one. I made it so that we output a different error
message for each. This makes it more clear, and in the case of more than
one, the error source location points at the second default clause,
rather than at the switch statement.
* Add functions to ProgramBuilder to more easily define switch and case
statements.
* Fix broken tests as a result of this change.

Requiring a temporary stack-allocated ast::Literal is an unpleasant requirement to generate a SPIR-V constant value.
GenerateU32Literal() was also creating an invalid AST - the type was U32, yet an an ast::SintLiteral was used.
Instead add Constant for holding a constant value, and use this as the map key.
This also removes the last remaining use of ast::NullLiteral, which will be removed in the next change.
