It's unlikely any real hardware supports this format. Hack in a fixed
fallback format for RGB8. We could consider implementing conditional
support by checking the VkPhysicalDevice properties.

This extends the Vulkan format support info in the RendererVk class
to distinguish between a Buffer and Texture format. This is closely
related to how Vulkan has separate format support bits for Linear
Textures, Optimal Textures, and Buffers. We probably won't need to
keep separate caps for Linear/Optimal, but it makes sense for Buffers
to eventually use the same format tables.

std::map lookups are already showing up as a hot spot during some
profile trace analysis. We can elimintate these by only doing a
single switch at the entry point level to convert the GL internal
format to an internal identifier or type info pointer.

This change doesn't completely fix the hot spot, since now we are
doing multiple switch statements, but it does remove the std::map
storage in TextureCapsMap. It replaces it with a flat std::array
indexed by angle::Format::ID, and gives us the option in the future
to eliminate all by one switch statement.

This should allow for a faster texture caps implementation in Vulkan.

This also fixes the missing ANGLE format entries for ETC1 compressed
formats.

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

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

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.
