enh(delphi) Improve handling of numeric literals

[Cirras]

Changes

• Add support for digit separators, which were introduced in Delphi 11
  • This is also allowed in FreePascal via {$modeSwitch underscoreIsSeparator+}
• Allow all digits to be omitted for hexadecimal and binary literals (i.e. $ and %)
  • This is an odd one, but it's allowed in Delphi
  • It produces a value of zero
• Add support for character strings with non-decimal numeric literals
  • e.g. #90 = #$5A = #&132 = #%01011010 = 'Z'
