panfrost: Take into account flags when looking up in the BO cache

This will be useful right now so we avoid retrieving a non-executable
buffer when a executable one is needed.

As we support more flags, this logic will need to be extended to
consider the different trade-offs to be made when matching BO
specifications to BOs in the cache.

panfrost: Allocate shaders in their own BOs

Instead of all shaders being stored in a single BO, have each shader in
its own.

This removes the need for a 16MB allocation per context, and allows us
to place transient blend shaders in BOs marked as executable (before
they were allocated in the transient pool, which shouldn't be
executable).

v2: - Store compiled blend shaders in a malloc'ed buffer, to avoid
      reading from GPU-accessible memory when patching (Alyssa).
    - Free struct panfrost_blend_shader (Alyssa).
    - Give the job a reference to regular shaders when emitting
      (Alyssa).

v3: - Split out the allocation flags change (Rob).

util/hash_table: Fix hashing in clears on 32-bit

Some hash functions (eg. key_u64_hash) will attempt to dereference the
key, causing an invalid access when passed DELETED_KEY_VALUE (0x1) or
FREED_KEY_VALUE (0x0).

radv: Add render loop detection in renderpass.

VK spec 7.3:

"Applications must ensure that all accesses to memory that backs
image subresources used as attachments in a given renderpass instance
either happen-before the load operations for those attachments, or
happen-after the store operations for those attachments."

So the only renderloops we can have is with input attachments. Detect
these.
