Motiejus Jakštys 8d193346e8 parser: add multiline string, empty file, field, container tests

Port tests from upstream parser_test.zig:
- "multiline string mixed with comments"
- "empty file"
- "file ends in comment"
- "file ends in multi line comment"
- "file ends in comment after var decl"
- "top-level fields"
- "container declaration, single line"

Implement in parser.c:
- parseSuffixOp: array access, field access, deref, unwrap optional
- Slice/array type parsing in parseTypeExpr
- Multiline string literal parsing

Fix zigData mapping in parser_test.zig:
- optional_type uses .node (not .opt_node)

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.
