This adds a fixed bias (-0.5) to the computed LOD of all
mip-mapped texture fetches. (Technically, to all texture
fetches, but that only matters for mip-mapped ones).
Clients can opt-in with a new GrContextOption.

The ultimate goal is to end up with "float" and "half", but this
intermediate step uses "highfloat" so that it is clear if I missed a
"float" somewhere. Once this lands, a subsequent CL will switch all
"highfloats" back to "floats".

On desktop, this saves just over 5% of the time in the SkSL compiler.
As written, the code will now build either way, so it's much easier to
switch back (or even have some platforms use SkString, if that's ever
required).

This has some knock-on effects in the generation of Android.bp from our GN files. See gn/gn_to_bp.py? We're seeing things like "tmp/tmpsBVycx/gen/" end up in the include search path in Android.bp, which obviously don't exist there...

The main issue was a use-after-free due to removing (and thus destroying)
the binary expression prior to re-adding part of it. Also cleaned up the
way dead assignments are handled and added the test that originally
