cmake/conan: Conditionally add target Boost::context

Addresses an issue with the two competing versions of Conan's Boost
package that are currently floating around.

Adds the Boost::context target only if it's recognized by CMake as a
target.

controllers/npad: Validate device handles before use

fsp_srv: Implement OpenDataStorageWithProgramIndex

maxwell_3d: Remove unused dirty_pointer array

aoc_u: Stub IPurchaseEventManager and its service commands

cmake: Fix generating CMake configs and linking with Boost

Fixes regression by 761206cf, causing
yuzu to not build on Linux with any version of Boost except a cached
1.73 Conan version from before about a day ago.

Moves the Boost requirement out of the `REQUIRED_LIBS` psuedo-2D-array
for Conan to instead be manually configured, using Conan as a fallback
solution if the system does not meet our requirements.

Requires any update from the linux-fresh container in order to build.

**DO NOT MERGE** until someone with the MSVC toolchain can verify this
works there, too.

Some games such as NEKOPARA Vol. 3 send invalid device handles when calling InitializeVibrationDevice. Introduce a check to validate the device handle before use.

common/file_util: Address review comments of #5174

travis/linux: Use correct ccache directory

nim: Stub IsLargeResourceAvailable

Changes the bound ccache directory to `/home/yuzu/.ccache` instead of
`/root/.ccache`, since the `/root` directory is not accessible by the
`yuzu` user in the guest container.

gl_shader_decompiler: Elide unnecessary copies within DeclareConstantBuffers()

Makes use of the VirtualDir and VirtualFile aliases across the board
instead of having a few isolated places that don't use it.

common/file_util: Let std::filesystem cast from UTF16 to std::string

Fix invalid encoding paths when iterating over a directory on Windows.

vfs_real: Fix CreateFile for files without a file extension

common/file_util: Fix and deprecate CreateFullPath, add CreateDirs

Fix CreateFullPath to have its intended previous behavior (whatever
that was), and deprecate it in favor of the new CreateDirs function.

Unlike CreateDir, CreateDirs is marked as [[nodiscard]] to avoid new
code ignoring its result value.

network, sockets: Replace `POLL_IN`, `POLL_OUT`, etc. constants with an `enum class PollEvents`

common/file_util: Make use of std::filesystem

Converts creation and deletion functions over to std::filesystem,
simplifying our file-handling code.

Notably with this, CopyDir will now function on Windows.

core: Remove unnecessary enum casts in log calls

applets: Resolve variable shadowing
