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.

These are intentionally discarded internally, since the rest of the
public API allows querying success. We want all non-internal uses of
these functions to be explicitly checked, so we can signify that we
intentionally want to discard the return values here.

We can simplify this function down into a single line with the use of
fmt. A benefit with the fmt approach is that the fmt variant of
localtime is thread-safe as well, making GetOsTimeZoneOffset()
thread-safe as well.
