When HEADER_GENERATOR was included in the DEPENDS section of custom
commands, msbuild assumed this was always modified. Changing this file
is not common so we can remove it from there.

Add automap feature for GC adapter

memory: Resolve a -Wdocumentation warning

install_dialog: Remove unused function prototype

game_list: Eliminate redundant argument copies 

memory doesn't exist as a parameter any more.

Allows the compiler to warn against cases where the return value isn't
used (which would be a bug).

This function doesn't have an implementation, so it can be removed to
prevent others from unintentionally using it.

Makes the naming consistent with the rest of the functions that are
present.

Several functions can be taken by const reference to avoid copies

control_flow: Make use of std::move in InsertBranch()

Places data structures where they'll eventually be moved to to avoid
needing to even move them in the first place.

Avoids unnecessary atomic increments and decrements.

General: Make use of std::nullopt where applicable

Allows some implementations to avoid completely zeroing out the internal
buffer of the optional, and instead only set the validity byte within
the structure.

This also makes it consistent how we return empty optionals.

ips_layer: Eliminate a redundant copy in Parse()

Prevents unnecessary copying of the line being parsed.

submission_package: Account for multi-content NSPs

renderer_opengl: Remove emulated mailbox presentation

hid: Implement Get/SetNpadHandheldActivationMode

Emulated mailbox presentation was causing performance issues on
Nvidia's OpenGL driver. Remove it.

Test: Decrease pad_update_ns

fermi_2d: Make use of designated initializers

Same behavior, less repetition. We can also ensure all members of Config
are initialized.

- Used in Clubhouse Games: 51 Worldwide Classics

configure_input_player: Fixes motion mapping using ConfigureButtonClick

configure_input_player: Re-add "Clear" context menu option

am: Stub GetPreviousProgramIndex

- Used in Super Mario 3D All-Stars

The context menu was removed in Mjölnir Part 1 as part of the input rewrite as we were unaware of it's usage statistics.
However, as this was the only way to clear the inputs of individual buttons, this PR will re-add it back in.

Previously we assumed a submission package can only contain one Program NCA with a single TitleID.
However, Super Mario 3D All-Stars contains four Program NCAs, each with their unique TitleIDs.
This accounts for the existence of multi-content games such as this one.
- Fixes booting Super Mario 3D All-Stars from the games list.

arm_dynarmic_cp15: Initialize member variables

service/sm: Eliminate dependency on the global system instance

service: Remove unused funcation

command_generator/nfp: Eliminate unnecessary copies

decoder/texture: Eliminate narrowing conversion in GetTldCode()

decode/image: Eliminate switch fallthrough in DecodeImage()

hid/configuration: Implement motion controls to HID
