PowerRename: Add Lookbehind (#7571)

* Add boost-regex library

* If enabled use boost lib for regex

Add property `_useBoostLib` to `CPowerRenameRegEx`. If enabled for
replacements with regular expressions the Boost Library is used instead
of the Standard Library.

* Extend signatures to create RegEx with Boost

Extend create and constructor singatures of `CPowerRenameRegEx` with an
option to enable (or disabled, which is default) the Boost Library.

* Verify Lookbehind fails with STD library

To verify that the boost library is disabled as expected, check if a
lookbehind fails.

* Add Unit tests for RegEx with Boost

Add unit tests to verify regex replacement with Boost Library. They are
copied and adapted from the Standard Library tests.

* Improve verify capturing groups test with Boost

It is possible to use a capturing group followed by numbers as
replacement if the group number is enclosed in curly braces.
Added test cases based on the Standard Library tests.

* Add useBoostLib to settings interface

* Get library option from settings object

* Reduce signatures of RegEx by "useBoost"

Remove the parameter added in 19105cf, as it became obsolete.

* Settings: Read useBoostLib from JSON file

* Add UseBoostLib Option to UI

* Boost Lib label states the regex syntax difference

* Fix Regex with Boost Lib tests

- Do not load settings another time in CPowerRenameRegEx ctor
- Set flag correctly in standard library regex tests

* Add "lookbehind" to dictionary

* change Library to lowercase, and also add a comment
