Properly stringify names in tests (#6279)

Update identifiers used in tests to use a format supported by the new text
parser, i.e. either the standard format with its limited set of allowed
characters or the non-standard `$"..."` format. Notably, any name containing
square or curly braces now uses the string format.

Input automatically updated with this script:

The printer is updated to properly escape names in more places as well. The
logic for escaping names is moved to a common location so that the type
printing logic in wasm-type.cpp can use it as well.
