[video_core] cpu buffer fix + kepler uploads / maxwell macro dirty tracking fixes

Addresses #4383.

Makes it so both the Qt and SDL frontends now share the same options (bar `-hlaunch` and `-qlaunch`).

-## eden
+There are two main applications, an SDL-based app (`eden-cli`) and a Qt based app (`eden`); both accept the same command line arguments.
 
 - `./eden <path>`: Running with a single argument and nothing else, will make the emulator look for the given file and load it, this behavior is similar to `eden-cli`; allows dragging and dropping games into the application.
-- `-g <path>`: Alternate way to specify what to load, overrides. However let it be noted that arguments that use `-` will be treated as options/ignored, if your game, for some reason, starts with `-`, in order to safely handle it you may need to specify it as an argument.
-- `-f`: Use fullscreen.
-- `-u <number>`: Select the index of the user to load as.
-- `-input-profile <name>`: Specifies input profile name to use (for player #0 only).
+- `--debug/-d`: Enter debug mode, allow gdb stub at port `1234`
+- `--config/-c`: Specify alternate configuration file.
+- `--fullscreen/-f`: Use fullscreen.
+- `--help/-h`: Display help.
+- `--game/-g <path>`: Alternate way to specify what to load, overrides. However let it be noted that arguments that use `-` will be treated as options/ignored, if your game, for some reason, starts with `-`, in order to safely handle it you may need to specify it as an argument.
+- `--multiplayer/-m`: Specify multiplayer options.
+- `--program/-p`: Specify the program arguments to pass (optional).
+- `--user/-u <number>`: Specify the user index.
+- `--version/-v`: Display version and quit.
+- `--input-profile/-i <name>`: Specifies input profile name to use (for player #0 only).
+- `--null-render/-n`: Forces the usage of the "Null" render backend irrespective of settings.
+- `--filter/-x`: Sets the debug log filter irrespective of settings.
+- `--singlecore/-s`: Forces single-core regardless of settings.
+
+Only the Qt frontend supports the following arguments:
+
 - `-qlaunch`: Launch QLaunch.
 - `-hlaunch`: Launch homebrew launcher `nx-hbloader`.
     - Requires a copy of Atmosphere to be extracted onto `sdmc`.
     - This is a shorthand for `<eden folder>/sdmc/atmosphere/hbl.nsp`.
 - `-setup`: Launch setup applet.
 
-## eden-cli
+`eden` (provided with `--room`), and `eden-room` supports the following options as well:
 
-- `--debug/-d`: Enter debug mode, allow gdb stub at port `1234`
-- `--config/-c`: Specify alternate configuration file.
-- `--fullscreen/-f`: Set fullscreen.
-- `--help/-h`: Display help.
-- `--game/-g`: Specify the game to run.
-- `--multiplayer/-m`: Specify multiplayer options.
-- `--program/-p`: Specify the program arguments to pass (optional).
-- `--user/-u`: Specify the user index.
-- `--version/-v`: Display version and quit.
-- `--input-profile/-i`: Specifies input profile name to use (for player #0 only).
-- `--null-render/-n`: Forces the usage of the "Null" render backend irrespective of settings.
-- `--filter/-x`: Sets the debug log filter irrespective of settings.
-- `--singlecore/-s`: Forces single-core regardless of settings.
+- `-n/--room-name`: The name of the room.
+- `-d/--room-description`: The room description.
+- `-s/--bind-address`: The bind address for the room.
+- `-p/--port`: The port used for the room.
+- `-m/--max-members`: The maximum number of players for this room.
+- `-w/--password`: The password for the room.
+- `-g/--preferred-game`: The preferred game for this room.
+- `-i/--preferred-game-id`: The preferred game-id for this room.
+- `-u/--username`: The username used for announce.
+- `-t/--token`: The token used for announce.
+- `-a/--web-api-url`: yuzu Web API url.
+- `-b/--ban-list-file`: The file for storing the room ban list.
+- `-l/--log-file`: The file for storing the room log.
+- `-h/--help`: Display this help and exit.
