unhandled_key_input changed to unhandled_button_input. Controls can set a 'shortcut_context' which they can then use to determine if their shortcuts should be triggered or not, based on if the viewport's focused GUI control is a child of their 'shortcut context'.
This check was there since the first commit in 2014, but a later feature added in 2018
with #17717 did not properly update the code while adding non animation-related code
in `perform_node_renames`.
Fixes#40532.
ToolButton has no redeeming differences with Button;
it's just a Button with the Flat property enabled by default.
Removing it avoids some confusion when creating GUIs.
Existing ToolButtons will be converted to Buttons, but the Flat
property won't be enabled automatically.
This closes https://github.com/godotengine/godot-proposals/issues/1081.
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.
This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.
There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).
Part of #33027.
Part of #33027, also discussed in #29848.
Enforcing the use of brackets even on single line statements would be
preferred, but `clang-format` doesn't have this functionality yet.
It changed name as part of the DisplayServer and input refactoring
in #37317, with the rationale that input no longer goes through the
main loop, so the previous Input singleton now only does filtering.
But the gains in consistency are quite limited in the renaming, and
it breaks compatibility for all scripts and tutorials that access
the Input singleton via the scripting language. A temporary option
was suggested to keep the scripting singleton named `Input` even if
its type is `InputFilter`, but that adds inconsistency and breaks C#.

Fixes#37690.
Switching between editors now requires holding Ctrl to avoid
conflicts with the new F2 shortcut.
The asset library can now be accessed by pressing Ctrl + F4
on Windows and Linux, or Alt + 4 on macOS.
This partially addresses #38139.
