Add a licenseRule.json file for checking of SPDX license identifiers6.7

The license test in qtqa reads this file
in order to check the validity of the license used.
This file reproduce the QUIP-18 [1] rules, with some exceptions.

Each entry in the file corresponds to a set of licensing rules.

A set of licensing rules can depend on the file ending,
registered in "file_pattern_ending". The last entry in the
file has no "file_pattern_ending", it sets the rules for the
files whose licensing does not depend on their ending.

The license to be used depends on the location
of the file within the Qt module repository.
Let's call this "<true_location>".
The  "<true_location>" can also correspond to a file name,
offering flexibility for exceptions to the rule.
The "<true_location>" are registered in "location".

For each "<true_location>" there is a
"file type" entry and a "spdx" entry.
The "spdx" entry gives the rule:
the expected license tag(s) in SPDX format
for the file ending (if applicable) and "<true_location>".
The "file type" informs on the QUIP-18 type
the tested file corresponds to. It is purely informational
for the reader.

The set of rules are tested in order of appearance
in the json file. For this reason, a more constraining
ending (like "special.txt") needs to appear in
a "file_pattern_ending" located before
the "file_pattern_ending" of a less constraining ending (like ".txt").
Also, a file ending cannot be present in two "file_pattern_ending".

"file_pattern_ending" and "spdx" should list strings.
"<true_location>" can be regular expressions.

During the test the deeper "<true_location>" are
checked first. The order is which they appear in the json file
does not matter.

To test this file, run
