file_util: Remove compiler version checks around is_trivially_copyable

externals: Update dynarmic

The minimum clang/GCC versions we support already support this. We can also
remove is_standard_layout(), as fread and fwrite only require the type to be
trivially copyable.

log: Remove old logging macros and functions

Just a basic update to keep it in sync

travis: Use Xcode 9.3 instead of 9.2

Now that the old macros are no longer used, we can remove all functionality related to them.

gl_shader_decompiler: Add GLSLRegisterManager class to track register state.

core/renderer_opengl: Replace usages of LOG_GENERIC with fmt-capable equivalents

Keeps the toolchains up to date.

general: Convert assertion macros over to be fmt-compatible

Implemented some useful interfaces needed for games.

frontends: Move logging macros over to new fmt-capable ones

common: Move logging macros over to new fmt-capable macros where applicable

input_common: Move old logging macros over to fmt-capable ones

core: Replace remaining old non-generic logger usages with fmt-capable equivalents

Shader decompiler prep for integer instructions

common: Remove chunk_file.h and linear_disk_cache.h

LOG_GENERIC usages will be amended in a follow-up to keep API changes separate from
interface changes, as it will require removing a parameter from the relevant function
in the VMManager class.

These are unused (and given chunk_file references Dolphin's >SVN< I doubt they were going to be used).

core/gdbstub: Move logging macros to new fmt-compatible ones

core/hw: Move logging macros over to fmt-capable ones

 Shaders: Implemented the FSET instruction.

 kernel: Migrate logging macros to fmt-compatible ones 

GPU: Partially implemented the 2D surface copy engine

file-sys: Move logging macros over to the new fmt-capable ones
