Refactor into four major components: 1. Common: Things shared among all other components. 2. Lang: P4-language-related components. 3. Runtime: Components required to run a P4 program. 4. Parser: Components for parsing a P4 program from source. Other components: 1. Macros 2. Tests 3. TreeSitterExtensions: Extra tree sitter functionality Signed-off-by: Will Hawkins <hawkinsw@obs.cr>
