Before this fix, the "cannot modify sprite/cannot lock sprite" message
was displayed instead of just dropping pixels.

This commit addresses the issue where the Shift+brush tool was not disabling the mouse stabilizer, leading to unintended behavior when previewing a line. This commit adds the necessary implementation to properly disable the stabilizer when Shift+brush tool is used. Additionally, the function DrawingState::disableMouseStabilizer() now calls ToolLoopManager::disableMouseStabilizer() to ensure the stabilizer is disabled correctly.
With https://community.aseprite.org/t/layers-become-empty-when-autosaving/22141
we found a couple of bugs where only 2 backed up versions of stored
objects were added in ObjVersions::add().
Also as ObjVersions has a limited space for 3 versions, it's a good
idea to ignore invalid binary files (files without the magic number
"FINE" as header). So now we only add valid versions to ObjVersions,
previously we could lead to a situation where 3 invalid binary
versions of the same object were added to the ObjVersions and a 4th
valid version were ignored.

ENABLE_UPDATER flag now only controls the "check update" portion of
the updater-lib. Probably the user agent string could be moved to the
ver-lib in the future.
Only in debug mode with TEST_BACKUP_INTEGRITY flag, we now don't
detect as a layer diff between the doc in memory and the restore doc
from backup if only some layer flags like visibility/collapse changed.
This refactor includes:
- In Lua now we can clone a custom brush with Brush(Image) and the new
brush doesn't share the image with the original one (added a new test
for this).
- Avoid creating extra images when it's not needed using
Brush::cloneWithExistingImages() (we can inject existing images in
the brush itself).
- Delete Brush-copy contructor & assign operator to use
Brush::clone() functions instead (which are more explicit).
- Some code from 12d8135264 (#4023)
reverted to avoid recreating brushes on left-click or in the brush
preview, i.e. moving the mouse (#4013 refers only to right-click, so
only on right-click we have to adjust the custom brush).
Before this fix to change the main color of the image brush,
it was necessary to choose a new color from the palette.
The secondary color can now also be used.
Also added some tests for image brushes.
This errors was reported in #4431: The Tx wasn't rolled back correctly
in case of a Lua error inside the transaction because Lua needs to be
compiled as C++ to avoid longjmps and support stack
unwinding (i.e. calling destructors).
If the user preferences file (aseprite.ini) contained a non-existent
language, the first option of the languages combo box was selected,
which might lead to a confusing situation where just opening the
preferences dialog will change from English to other
language (non-English, the first language in the combobox).
This was mainly found in SpriteSizeJob crash reports. In these reports
deleted image buffers were still used to paint the Editor canvas
because the doc was write-locked in the main thread (same thread where
the canvas is painted). This produced a re-entrant lock in the
Editor::onPaint() as we can still read-lock from the same thread where
we write-locked the doc.
With this change we write-lock the doc from the SpriteJob background
thread (not the main thread) only if it's necessary (i.e. when the doc
is not already locked in the main thread, e.g. when running a script).
This makes that the main thread (Editor::onPaint) cannot read the doc
until we finish the whole SpriteJob transaction/Tx.
One fix that this patch includes for #4367 (crash by unhandled
CannotWriteDocException exception) is when we drag-and-drop a tag
border to resize its limits. This is a fix for that case but we don't
know if this include all cases of #4367 crashes (so we cannot close
the issue).
Anyway we have added some try { } catch in cases where it's better to
avoid propagating the exception, e.g. in
MovingSelectionState::onLeaveState() to avoid throwing exceptions in
Editor::backToPreviousState() which might be problematic in several
cases. (Maybe related to #2829?)
