This is the first batch of a series implementing faster media source resolution required to workaround an Unreal Engine race condition present in some games, and deterministic stream ordering that decodebin / parsebin cannot provide, which is required to expose the streams in native order, for compatibility in several other applications.
I pushed the full series as a branch here: https://gitlab.winehq.org/rbernon/wine/-/commits/mr/wg-source-part-one
Note that this full series is also a first step in the direction of having a simpler demuxer interface, which will be required in the future for compatibility with applications that build MF or DirectShow pipelines directly and expect the relevant components to behave as a demuxer and expose compressed media types. For now it only delays the use of wg_parser to whenever the media source is started, and matches the non-ordered streams using their media types and tags. This is a best effort solution but I don't think we can do much better for the moment.

Based on [a patch](https://www.winehq.org/mailman3/hyperkitty/list/[email protected]… by Jinoh Kang (@iamahuman) from February 2022.
I removed the need for the event object and implemented fast paths for Linux.
On macOS 10.14+ `thread_get_register_pointer_values` is called on every thread of the process.
On Linux 4.14+ `membarrier(MEMBARRIER_CMD_GLOBAL_EXPEDITED, ...)` is used.
On x86 Linux <= 4.13 and on other platforms `madvise(..., MADV_DONTNEED)` is used, which sends IPIs to all cores causing them to do a memory barrier.

Currently GetFileType() ends up returning the file type solely based on Unix fd type if it gets it from server. The problematic case is when our process gets a pipe or socket fd as a stdin or stderr from Unix. The server object which gets created through wine_server_fd_to_handle is a regular file regardless of the underlying Unix fd type. It probably can't be anything else, at least for pipes, as the pipe should have both ends but we have only one in this case.
That causes problems, e. g., with libuv (used, e. g., by Vampire Survivors). It checks stdout handle type and if it is pipe it tries to do SetNamedPipeHandleState() on it and does not tolerate the failure.
It looks more sensible to me to report all the pipes and sockets created through wine_server_fd_to_handle() as regular files as that matches the server objects we have for them. When that is not the case we should get the correct type from server fd type.

Strings are opaque objects in HLSL. This implements recognizing string
literals and the `string` type.
This should fix the bug marked below but I'm not sure how to get my
hands on a copy of Lego Star Wars Saga to test it properly.
This is a super-duper draft MR; I'm certain there's problems with it.
I do at least have a passing test, though.

As _WINE_HWND_STYLE and _WINE_HWND_EXSTYLE respectively.
Gamescope parses these to make smarter decisions about what window
to primary focus, or to treat as a dropdown/overlay.
This was originally a Proton commit by Remi Bernon, however,
it would definitely be nice to have support for Gamescope focusing
correctly under upstream Wine as well.
Fixes a bunch of games/launchers run with Wine under Gamescope.

The idea I have is to use this module to declare class stubs until there is a good reason to split them to dedicated modules. WinRT modules aren't usually loaded directly, and instead the registry is queried to figure which module to load for which class.
This would help avoiding unnecessary proliferation of stub WinRT modules, while at the same time allowing to factor WinRT foundation code (such as vector / async, etc...) between the modules that seem to deserve to be implemented separately.
The relevant classes could then be split out to dedicated modules on a as-needed basis, when they get fleshed out.

Shader Model 6 introduces a 16-bit float (half) type, and 16-bit and 64-bit integer types. Storing extra info in the type enum simplifies checking if a type is any integer, floating point or numeric type, and the declaration of SPIR-V types. The benefits depend on using enum vkd3d_data_type in the backend instead of vkd3d_shader_component_type.
Patch 2 is difficult to split because types typically flow through to vkd3d_spirv_get_type_id(), so partial changes would require new calls to conversion functions which would be deleted again later.

v5: vkd3d-shader/spirv: Use enum vkd3d_data_type instead of vkd3d_shader_component_type.

The problem is that registry save is a very heavy operation (scheduled each 30sec in wineserver) during which server doesn't process any requests and the whole prefix is stalled for the duration of the operation.
For some reference, the process takes from 50-100ms here up to 1-1.5sec with default initial registry (after some registry modifications which trigger actual registry flush), depending on the filesystem type and state (as huge time may be spent in file close / rename). With the same registry after this patchset the server part (flush_key returning the whole registry data) is taking ~4-5mcs, measured from the client side so that already includes data transfer.
