Christian Grasser ad79718fc8 Update to scintilla 5.5.2 & Lexilla 5.4.0 
Release 5.5.2 ( https://www.scintilla.org/scintilla552.zip )

    Released 21 August 2024.
    Add SCI_SETCOPYSEPARATOR for separator between parts of a multiple selection when copied to the clipboard. Feature #1530.
    Add SCI_GETUNDOSEQUENCE to determine whether an undo sequence is active and its nesting depth.
    Add SCI_STYLESETSTRETCH to support condensed and expanded text styles.
    Add SCI_LINEINDENT and SCI_LINEDEDENT. Feature #1524.
    Fix bug on Cocoa where double-click stopped working when system had been running for a long time.
    On Cocoa implement more values of font weight and stretch.

Release 5.4.0 ( https://www.scintilla.org/lexilla540.zip )

    Released 21 August 2024.
    Inside Lexilla, LexerModule instances are now const. This will require changes to applications that modify Lexilla.cxx, which may be done to add custom lexers.
    Lexer added for TOML "toml".
    Bash: Handle backslash in heredoc delimiter. Issue #257.
    Progress: Fix lexing of nested comments. Pull request #258.
    Force lower-casing of case-insensitive keyword lists so keywords match in some lexers. Issue #259.

Close #15564

// Scintilla source code edit control
// @file LexAU3.cxx
// Lexer for AutoIt3 https://www.autoitscript.com/site/
// by Jos van der Zande, jvdzande@yahoo.com
//
// Changes:
// March 28, 2004 - Added the standard Folding code
// April 21, 2004 - Added Preprosessor Table + Syntax Highlighting
// Fixed Number highlighting
// Changed default isoperator to IsAOperator to have a better match to AutoIt3
// Fixed "#comments_start" -> "#comments-start"
// Fixed "#comments_end" -> "#comments-end"
// Fixed Sendkeys in Strings when not terminated with }
// Added support for Sendkey strings that have second parameter e.g. {UP 5} or {a down}
// April 26, 2004 - Fixed # pre-processor statement inside of comment block would invalidly change the color.
// Added logic for #include <xyz.au3> to treat the <> as string
// Added underscore to IsAOperator.
// May 17, 2004 - Changed the folding logic from indent to keyword folding.
// Added Folding logic for blocks of single-commentlines or commentblock.
// triggered by: fold.comment=1
// Added Folding logic for preprocessor blocks triggered by fold.preprocessor=1
// Added Special for #region - #endregion syntax highlight and folding.
// May 30, 2004 - Fixed issue with continuation lines on If statements.
// June 5, 2004 - Added comma to Operators for better readability.
// Added fold.compact support set with fold.compact=1
// Changed folding inside of #cs-#ce. Default is no keyword folding inside comment blocks when fold.comment=1
// it will now only happen when fold.comment=2.
// Sep 5, 2004 - Added logic to handle colourizing words on the last line.
// Typed Characters now show as "default" till they match any table.
// Oct 10, 2004 - Added logic to show Comments in "Special" directives.
// Nov 1, 2004 - Added better testing for Numbers supporting x and e notation.
// Nov 28, 2004 - Added logic to handle continuation lines for syntax highlighting.
// Jan 10, 2005 - Added Abbreviations Keyword used for expansion
// Mar 24, 2005 - Updated Abbreviations Keywords to fix when followed by Operator.
// Apr 18, 2005 - Updated #CE/#Comment-End logic to take a linecomment ";" into account
// - Added folding support for With...EndWith
// - Added support for a DOT in variable names
// - Fixed Underscore in CommentBlock
// May 23, 2005 - Fixed the SentKey lexing in case of a missing }
// Aug 11, 2005 - Fixed possible bug with s_save length > 100.
// Aug 23, 2005 - Added Switch/endswitch support to the folding logic.
// Sep 27, 2005 - Fixed the SentKey lexing logic in case of multiple sentkeys.
// Mar 12, 2006 - Fixed issue with <> coloring as String in stead of Operator in rare occasions.
// Apr 8, 2006 - Added support for AutoIt3 Standard UDF library (SCE_AU3_UDF)
// Mar 9, 2007 - Fixed bug with + following a String getting the wrong Color.
// Jun 20, 2007 - Fixed Commentblock issue when LF's are used as EOL.
// Jul 26, 2007 - Fixed #endregion undetected bug.
