Instead of baking in a relative path and expecting the app to run from
a fixed directory, we can change the CWD at runtime so the layers can
load relative to the current executable directory.

Future alternatives could include modifying the layers SDK to provide
a path dynamically, but for now the relative paths must be baked in
at compile-time.

Since common is shared through all ANGLE code (libANGLE/tests/samples)
this is the most general place for these utils, and will give libANGLE
access to them. We'll need them to get the current executable dir for

This also means we'll need to fix the global static variable use when

This CL moves the varying packing from the D3D layer up to Program.
This is necessary for WebGL validation, and gives us consistency
for the various back-ends. There may be some additional cleanup work
on the VaryingPacking class, because it does some work that is D3D-
specific.

WebGL requires strict varying packing. Instead of allowing success
unconditionally, it's an explicit error to succeed to pack a set of
varyings that the sample algorithm would fail to pack.

Introduce a new packing mode option to the varying packing class to
handle this different packing style, while keeping our old more
relaxed packing method for ES code.
