This moves the Vulkan format table to dynamically generated, but
keeps it easily indexed. Because Vulkan format support is not able
to be fully determined until runtime, we'll need a dynamic way to
build the table. The most straight-forward way seems to be to keep
a copy of the full table in the Renderer. Initializing it once at
startup makes it a bit slower to init, but saves us from any threading
shenanigans with lazy init when (and if) we ever support multi-
threaded Contexts.

The native HLSL compiler does not accept switch statements with an
empty statement list. The simplest way to accommodate this is to
simply remove them from the AST after parsing and some initial
pruning.

This is done by the new RemoveEmptySwitchStatements traverser. It
preserves init statements of switch statements in case they have side
effects. So for example

switch(++i) {}

gets translated to

++i;

Even an empty statement like ";" is a statement according to the
grammar. They should not be allowed in switch statements before the
first case statement, but on the other hand a switch statement that
has just an empty statement after the last statement is valid.

Now the parser creates AST nodes from empty statements so that we can
validate switch statements correctly. However, they are pruned shortly
after parsing completes in PruneNoOps, so they don't affect further
processing of the AST.
