Before this patch, deferred location in operation like `test.pretty_printed_region` would
break the parser, and so the IR round-trip.

The new form of printing attribute in the declarative assembly is eliding the `#dialect.mnemonic` prefix to only keep the `<....>` part.

The functionality already exists in AsmParser to parse optional ArrayAttrs and
StringAttrs, but only if they are added to a NamedAttrList. This moves the
code to parse an optional attribute and add it to an list into a common
template, and exposes the simpler functionality of just parsing the optional
attributes.

This adds a new parser and printer for text which may be a keyword or a
string. When printing, it will attempt to print the text as a keyword,
but if it has any special or non-printable characters, it will be
printed as an escaped string. When parsing, it will parse either a
valid keyword or a potentially escaped string. The printer allows for an
empty string, in which case it prints `""`.
This new function is used for printing the name in NamedAttributes, and
for printing the symbol name after the `@`. In CIRCT we are using this
to print module port names, which are conceptually similar to named
function arguments.

This has a few benefits:
* It allows for defining parsers/printer code blocks that
can be shared between operations and attribute/types.
* It removes the weird duplication of generic parser/printer hooks,
which means that newly added hooks only require touching one class.
