Datasette uses non-standard quoting for identifiers

[cldellow]

Related to #2001, but where #2001 was about literals, this is about identifiers

From https://www.sqlite.org/lang_keywords.html:

"keyword" A keyword in double-quotes is an identifier.
[keyword] A keyword enclosed in square brackets is an identifier. This is not standard SQL. This quoting mechanism is used by MS Access and SQL Server and is included in SQLite for compatibility.

Datasette uses this quoting here --

datasette/datasette/utils/__init__.py

Lines 345 to 349 in 0b4a286

	def escape_sqlite(s):
	if _boring_keyword_re.match(s) and (s.lower() not in reserved_words):
	return s
	else:
	return f"[{s}]"

, in some of the other DB access code, and in some of the test fixtures.

Migrating to standard double quote identifiers would make it easier to get Datasette working with alternative backends
