LI(23)P62014r2: Add EditorConfig and reformat ASN.1 and XML

See merge request li/schemas-definitions!71

Reformat the .xml and .xsd files using
	env XMLLINT_INDENT="    " xmllint --encode UTF-8 --format FILENAME.xml

Notable (non-whitespace) changes to the existing files:
- Ensure the <xml ...> header has encoding="UTF-8".
- <xs:schema ...> collapsed to one line and some attribute reordered.
- Empty tags are converted to self-closing tags. E.g.
	<xs:element name="Name" type="Type"></xs:element:>
  becomes
	<xs:element name="Name" type="Type"/>
- Some xmlns related attributes are reordered.

Per discussion with rapporteurs and Mark Canterbury.

Reformat the .xml and .xsd files:
- tabs converted to 4 spaces
- no trailing whitespace

No difference to previous when  git diff -b / --ignore-space-change

Reformat the .asn files:
- 4 space indenting, including ensuring fields line up
- no tabs
- no trailing whitespace

No difference to previous when  git diff -b / --ignore-space-change
except for removal of some trailing blank lines.

Provide .editorconfig file.

Globally, use UNIX-style formatting:
- UNIX linefeed for end of line
- Ensure files have a trailing newline.

.asn, .asn1, .xml, .xsd:
- 4 space indents (not tab)
- Trim trailing whitespace
