Motiejus Jakštys 1a8bb5ac10 parser: add fn params, return, call args, enum literal tests

Port tests from upstream parser_test.zig:
- "trailing comma in fn parameter list" (all combinations)
- "enum literal inside array literal"
- "builtin call with trailing comma"

Implement in parser.c:
- parseParamDeclList: full parameter parsing with names, comptime,
  noalias, doc comments, varargs
- parseFnProto: fn_proto_multi, fn_proto_one, fn_proto with
  align/addrspace/section/callconv
- parseSuffixExpr: function call with arguments
- parsePrimaryExpr: return, comptime, nosuspend, resume expressions
- parseAddrSpace, parseLinkSection, parseCallconv: full parsing
- Use OPT() macro for OptionalIndex encoding in extra data

Testing

Quick test:

zig build

Debugging tips

Test runs infinitely? Build the test program executable:

$ zig build test -Dno-exec

And then run it, capturing the stack trace:

gdb -batch
-ex "python import threading; threading.Timer(1.0, lambda: gdb.post_event(lambda: gdb.execute('interrupt'))).start()"
-ex run
-ex "bt full"
-ex quit
zig-out/bin/test

You are welcome to replace -ex "bt full" with anything other of interest.
