Add SystemVerilog filetype

Add SystemVerilog filetype and syntax highlighting:
- Create SystemVerilog filetype in Geany.
- Set it to use the existing Verilog lexer and ctags parser
  (which already supported both Verilog and SystemVerilog).
- Create filedefs file, including all the standard keywords
  from SystemVerilog-2017 (IEEE Std 1800-2017).

The ctags parser is currently underutilized, since classes and other
SystemVerilog constructs are tagged but not shown in the Symbols panel.
These will be added in a future commit.
