Revert "gallium: Fix big-endian addressing of non-bitmask array formats."

This reverts the functional part of commit
d17ff2f7f1864c81c1e00d04baf20f953c6d276a, leaving the unit test for
mesa/pipe agreement on what's an array.

The issue is that the util_channel_desc.shift values on array formats are
not used for bit addressing in memory, they're bit addressing within a
word treating a pixel of the format as a native type, as seen by
llvmpipe's use of the values to do shifts (see
lp_build_unpack_arith_rgba_aos() for example).  This means the values are
nonsensical for 3-byte RGB, but then llvmpipe doesn't expose those formats
so it works out.

I still want to clean up our big-endian format handling at some point, but
let's fix the s390x regression first, sort out our format unit tests in
CI, then be able to refactor with confidence.

This still isn't great as-is, but it seems to work. In the future, we

freedreno/ir3: put the conversion back for half const to the right place.

The previous commit leads to match immed values unexpectedly.

This makes constlen for each shader including bvert wrong.
Also fixes atan2 for mediump deqp tests.

Fixes: cbd1f47433b ("freedreno/ir3: convert back to 32-bit values for half constant registers.")
v2: Move conversion up above fabs/fneg modifier handling as well.

freedreno/ir3: Add cat4 mediump opcodes

A sequence like:

freedreno: android: fix build failure on android due to python version

The freedreno gen_header.py script now only works under python3.
It contains a "print()" call which prints a blank line under python3
but prints "()" under python2.7.

However the Android build currently uses python2.

This leads to incorrect code generation and a later build error.
