[Parser] Enable the new text parser by default (#6371)

The new text parser is faster and more standards compliant than the old text
parser. Enable it by default in wasm-opt and update the tests to reflect the
slightly different results it produces. Besides following the spec, the new
parser differs from the old parser in that it:

 - Does not synthesize `loop` and `try` labels unnecessarily
 - Synthesizes different block names in some cases
 - Parses exports in a different order
 - Parses `nop`s instead of empty blocks for empty control flow arms
 - Does not support parsing Poppy IR
 - Produces different error messages
 - Cannot parse `pop` except as the first instruction inside a `catch`
