Add the necessary CMake code to copy the contents in a string source
shader (GLSL or GLASM) to a header file then consumed by video_core
files.

This allows editting GLSL in its own files without having to maintain
them in source files.

For now, only OpenGL presentation shaders are moved, but we can add
GLASM presentation shaders and static SPIR-V generation through
glslangValidator in the future.

This allows us passing any type of string and hinting the length of the
string to the OpenGL driver.

web_service: Move web_result.h into web_service

core_timing: Resolve sign conversion warning

Same behavior, minus unnecessary zeroing out of the pointer.

This constant is only ever assigned to downcount, which is a s64, not a
u64.

This is the only place it's actively used. It's also more appropriate
for web-related structures to be within the web service target.
Especially given this one doesn't rely on anything in the common
library.

There's no need to translate an empty string. This just gives
translators unnecessary work.

Migrates a remaining common file over to the Common namespace, making it
consistent with the rest of common files.

This also allows for high-traffic FS related code to alias the
filesystem function namespace as

namespace FS = Common::FS;

for more concise typing.
