The sampler was simply not declared in that case, as if the uniform
was unused in the shader, so making sure structures containing
samplers call samplerRegister solves this issue. It was working
properly if the sampler was used anywhere else in the shader, but
failed when the only use in the shader was being passed as an
argument to a function through a containing structure.

Added a unit test since this isn't covered by dEQP.

Fixes 2 WebGL tests:

When libEGL and either libGLESv2 or libGLES_CM are in a different
folder from the executable's folder, libEGL wasn't successfully
finding libGLESv2/libGLES_CM (or vice versa). Since these libraries
are generally in the same folder, using the current library's folder
as a starting location to find another library solves this issue.

This cleans up a problem that was introduced by
https://swiftshader-review.googlesource.com/17188

LOCAL_VENDOR_MODULE was first supported on O, so when we build
SwiftShader on earlier branches the libraries land in /system.
The fix in the Android.mk files would be complicated and would revert
some of the cleanup, and would cause issues for 64 bit only builds.
While it would be possible to extend the original approach, it just
seems cleaner to check in /system at runtime.

Convert packed types to the next greater non-packed component type.
Specifically, when the red component has fewer than 8 bits, use the
corresponding sized internal format with 8-bit components.

Note that this is still not fully compliant.
The OpenGL ES 3.0 spec section 3.8.5 states that:

If internalformat is unsized, the internal format of the new texel array is determined
by the following rules, applied in order. If an effective internal format exists
that has
1. the same component sizes as,
2. component sizes greater than or equal to, or
3. component sizes smaller than or equal to
those of the source buffer’s effective internal format (for all matching components
in internalformat), that format is chosen for the new image array, and this is also
the new texel array’s effective internal format.

This means that in theory when copying an RGBA4 framebuffer into an RGB
texture, the effective internal format should be RGB565, not RGB8.
However, dEQP does not enforce this, and ANGLE always assumes
UNSIGNED_BYTE components.
