appveyor: Add support for meson as well as scons on windows

This job uses the vs2017 backend of meson (msbuild) as opposed to the
ninja backend used on MacOS and Linux.

v7: - rebase on master
    - remove llvm (we'll add that back later)
    - remove cygwin (we'll add that back later too)
v6: - rebase on master, including the addition of cygwin
    - consolidate 3 appveyor patches into this one patch
v5  - use the new b_vscrt option instead of manually specifying the crt
v4: - rebase on python3 generators
    - cache meson wraps
    - Build x86 instead of x86_64, since that's what the pre-built LLVM
      is
    - update to vs2017 from vs2015
    - set the default-library to static
    - use the new vscrt override
    - add the /m switch to msbuild to make the build somewhat faster

glsl/tests: Handle no-exec errors

Currently meson doesn't correctly handle passing compiled binaries to
scripts in tests. This patch looks to the future (0.53) when meson will
have this functionality, but also immediately it fixes these tests in
cross compiles by causing them to return 77, which meson interprets as
skip.

meson: add switches for SWR with MSVC

This makes two changes for SWR,

The first is that it reorders the arguments to try to put the ICL ones
first. This is required to support older versions of meson that don't
add enough "error in this case" switches to ICL, which causes it to
happy accept -mavx (for example) even though it doesn't support them,
resulting in compilation failures.

The second is to fix the names of the libraries, setting the soversion
to '' will result in <lib>.dll, instead of <lib>-0.dll. Since these are
not versioned dll's, but implement an internal API we should communicate
that. It's also what scons does.

intel/tools: Use common code for GGTT address allocation.

We want to be able to create contexts on demand, and increase the GGTT
as needed for that. Use the aub_map_ggtt() function for that.

intel/tools: Factor out GGTT allocation.

We want to reuse it in execlists_setup().

v2: Rename it to write_ggtt_ptes() (Lionel).
v3: Rename it to aub_map_ggtt() (Lionel).

radv: use a compute shader for copying timestamp query results

When the timestamp is not ready (ie. UINT64_MAX), the availabily bit
should be zero. The previous code used to copy the timestamp value
as the availabily bit and that's completely wrong.

Because it's not that simple to emit a conditional with the CP, the
driver now uses a compute shader for copying timestamp query results.

Fixes dEQP-VK.pipeline.timestamp.misc_tests.reset_query_before_copy.
