soong: add support for module specific lexer flags
To support module specific lexer flags, this follows the same strategy
as the yacc flags:
- add LexProperties to the BaseCompilerProperties
- propagate those flags to the generator generation (i.e. genLex)
- add a placeholder for custom flags
- replace the placeholder with the concatenated flags
This might not support escaping very well, but I figured that this is a
very edge case. Support for escaping etc. could be added later on.
