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.

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.

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.
