[v2] Devtools tag doesn't enable default context-menu

[mmghv]

Description

Now that -devtools tag adds a hotkey, it doesn't need to enable the default context-menu in production, so only the EnableDefaultContextMenu option enables it in production.

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

Isn't really considered a breaking change since it doesn't affect the core functionality of the application.

How Has This Been Tested?

When EnableDefaultContextMenu is false or not set:

command	Devtools (CTRL/CMD+SHIFT+F12)	Default context-menu (right-click inside an input)
wails build	Not Available	Not Available
wails build -devtools	Available	Not Available
wails build -debug	Available	Available Everywhere
wails dev	Available	Available Everywhere

When EnableDefaultContextMenu is true:

command	Devtools (CTRL/CMD+SHIFT+F12)	Default context-menu (right-click inside an input)
wails build	Not Available	Available (No inspect option)
wails build -devtools	Available	Available (with inspect option)
wails build -debug	Available	Available Everywhere
wails dev	Available	Available Everywhere

Tested on Linux, great news, the devtools can be opened with the hotkey while the default context-menu is disabled, contrary to my previous tests on Linux, so we could later add an option to disable the hotkey and expose a runtime method to open the devtools with a password or something (but the default context-menu have to be disabled then).

@leaanthony Please test on Mac when you have the time.
