video_core: gl_shader_decompiler: Fix implicit fallthrough errors.

loader/nso: Resolve moves not occurring in DecompressSegment

service: hid: npad: Fix implicit fallthrough errors.

service/time: Minor changes

memory/slab_heap: Make use of static_cast over reinterpret_cast

This is already initialized within the class body.

This doesn't modify internal member state.

Many of these implementations are used to implement a polymorphic
interface. While not directly used polymorphically, this prevents
virtual destruction from ever becoming an issue.

externals: Update fmt to 6.2.0

common/file_util: Allow access to files on network shares

Casting from void* with static_cast is permitted by the standard, so we
can just make use of that instead.

Given the std::vector was const, an automatic move out of the function
could not occur.

We can allow automatic return value optimizations to occur by making the
buffer non-const.

video_code: Fix implicit switch fallthrough.

Since yesterday, this breaks the build on linux.
So let's fix it.

Keeps the library up to date.

Revert "gl_shader_cache: Use CompileDepth::FullDecompile on GLSL"

file_util: Early-exit in WriteArray and ReadArray if specified lengths are zero

Implement a new virtual memory manager

gl_query_cache: Resolve use-after-move in CachedQuery move assignment operator

- Should be no functional changes.

- Includes removing some service impls. that are untested.

- Includes removing some SVC impls. that are untested.

- Fixes Super Smash Bros. Ultimate.
