1ac1c0843f treewide: Replace usage of macro DEBUG with MESA_DEBUG when possible 
This is achieved by the following steps:

#ifndef DEBUG => #if !MESA_DEBUG
defined(DEBUG) => MESA_DEBUG
#ifdef DEBUG => #if MESA_DEBUG

This is done by replace in vscode

excludes
docs,*.rs,addrlib,src/imgui,*.sh,src/intel/vulkan/grl/gpu

These are safe because those files should keep DEBUG macro is already excluded;
and not directly replace DEBUG, as we have some symbols around it.

Use debug or NDEBUG instead of DEBUG in comments when proper

This for reduce the usage of DEBUG,
so it's easier migrating to MESA_DEBUG

These are found when migrating DEBUG to MESA_DEBUG,
these are all comment update, so it's safe

Replace comment /* DEBUG */ and /* !DEBUG */ with proper /* MESA_DEBUG */ or /* !MESA_DEBUG */ manually

DEBUG || !NDEBUG -> MESA_DEBUG || !NDEBUG
!DEBUG && NDEBUG -> !(MESA_DEBUG || !NDEBUG)

Replace the DEBUG present in comment with proper new MESA_DEBUG manually

79f47249e8 llvmpipe: Align persistent mappings to page size 
KVM requires memory mapping to be aligned to page size, otherwise it
refuses to do the mapping. In particular this causes KVM mapping errors
when llvmpipe is used by virtio-gpu on host and guest tries to map buffer
that has a persistent mapping, i.e. it tries to map the llvmpipe's host
blob/buffer. Mesa virgl driver uses host blobs only for the buffers with
persistent mapping, hence let's align buffer allocations to the page size
when the persistence flag is set to fix the KVM fault.

9102921109 llvmpipe: Add handle export for resource_get_param 
mesa/mesa@2dcc9c7f54 from mesa/mesa!6639 added a resource_get_param
hook for llvmpipe, which was nice since it gave lavapipe more features.
One of those features was not exporting llvmpipe textures, so those
parts were stubbed out and landed in an assert(0).

This completely broke kms_swrast (llvmpipe+GBM) on non-release builds,
since that definitely does need to export llvmpipe textures.

The query codepath which caused this explosion does fall back to
resource_get_handle() - which is how it worked previously - but not all
callers do this, so just do what all other drivers implementing
resource_get_param() do and open-code the translation.
