buffer_block: Remove unnecessary includes

Prevents logic errors from occurring from unused values.

Reduces the amount of dependencies the header pulls in.

hle: Type check ResponseBuilder::Push arguments, and fix use in vi.cpp

fmt now automatically prints the numeric value of an enum class member
by default, so we don't need to use casts any more.

Reduces the line noise a bit.

Fix "explicitly defaulted but implicitly deleted" warning

`PhysicalCore`'s move assignment operator was declared as `= default`,
but was implicitly deleted because `PhysicalCore` has fields
of reference type.  Switch to explicitly deleting it to avoid a Clang
warning.

The move *constructor* is still defaulted, and is required to exist due
to the use of `std::vector<PhysicalCore>`.

- Add a type check so that calling Push with an invalid type produces a
  compile error rather than a linker error.

- vi.cpp was calling Push with a variable of type `std::size_t`.
  There's no explicit overload for `size_t`, but there is one for `u64`,
  which on most platforms is the same type as `size_t`.  On macOS,
  however, it isn't: both types are 64 bits, but `size_t` is `unsigned
  long` and `u64` is `unsigned long long`.  Regardless, it makes more
  sense to explicitly use `u64` here instead of `size_t`.

video_core: Adjust `NUM` macro to avoid Clang warning

nvdrv: Remove useless re-declaration of pure virtual methods that were already declared in the superclass

The previous definition was:

    #define NUM(field_name) (sizeof(Maxwell3D::Regs::field_name) / sizeof(u32))

In cases where `field_name` happens to refer to an array, Clang thinks
`sizeof(an array value) / sizeof(a type)` is an instance of the idiom
where `sizeof` is used to compute an array length.  So it thinks the
type in the denominator ought to be the array element type, and warns if
it isn't, assuming this is a mistake.

In reality, `NUM` is not used to get array lengths at all, so there is no
mistake.  Silence the warning by applying Clang's suggested workaround
of parenthesizing the denominator.

game_list_p: Resolve deprecated usage of QVariant operator<

On Apple platforms, FALSE and TRUE are defined as macros by
<mach/boolean.h>, which is included by various system headers.

Note that there appear to be no actual users of the names to fix up.

Specifically:

    const auto size = sdl2_config->GetInteger("System", "users_size", 0);

The variable is never used, producing a warning.  I wondered if this
ought to be assigning something to in `Settings`, but nothing else in
the codebase ever mentions a setting called "users_size", so I guess
it's safe to remove...

Cleans out the rest of the occurrences of variable shadowing and makes
any further occurrences of shadowing compiler errors.

This is designated as obsolete in Qt's docs (see:
https://doc.qt.io/qt-5/qvariant-obsolete.html#operator-lt)

video_core: Resolve more variable shadowing scenarios pt.2

Migrates the video core code closer to enabling variable shadowing
warnings as errors.

This primarily sorts out shadowing occurrences within the Vulkan code.
