36aa48ce36 [tint][ir] Clean up tests
Remove the direct use of BuilderImpl from TestHelperBase to cut down the amount
of internal state management required by the tests, and removing confusing
conflation between the BuilderImpl and Builder.

This change removes the following methods from TestHelperBase:
* CreateBuilder()
* InjectFlowBlock()
* CreateEmptyBuilder()
* FlowNodeForAstNode()

Tests now just use FromProgram() function for testing AST -> IR.

The downside to the black-box testing is that the per-method granularity of the
unit testing increases to whole FromProgram() granularity. However, my personal
opinion is that this is more than offset by the lack of state leakage from the
implementation to the tests.

a8236a5529 tint/ir: Remove value id field.
There's a few reasons for this change:
* Not all values have identifiers, and carrying redundant fields is
  inefficent.
* Not all IDs will be integers - much like LLVM IR and SPIR-V, we will
  likely want to disassemble with textual identifiers, so a uint32_t
  is not ideal, and a std::string is even more bloat for each value.
* Transforms don't use identifiers, but instead raw pointers. We don't
  want to encourage using IDs as they're simply a less-efficient way to
  refer to values.
* This makes values consistent with types and flow-control blocks, as
  they will both have their disassembly ID generated by the
  disassembler.

The next step will be to add a hashmap to the module so that
pre-declared value names can be stored out-of-band.

63716c55cc [ir] Spit builder_impl tests.
This Cl splits apart the builder_impl test file in order to make it
easier to determine what has been tested.
