tdf#150877: Add support for Kamenický and Mazovia encodings

...as referenced e.g. at
<https://docs.microsoft.com/en-us/previous-versions/visualstudio/foxpro/aa975345(v=vs.71)>
"Code Pages Supported by Visual FoxPro".  That source lists those two encodings
with "code page" values 895 and 620, resp. (which might be what we call "Windows
code pages" in include/rtl/tencinfo.h) and "code page identifier" values 0x68
and 0x69, reps. (which might be what we call "Windows charsets" in
include/rtl/tencinfo.h.  But I deliberately left these two new
RTL_TEXTENCODING_* values without any mappings to such Windows codepages etc.,
as I didn't find any authoritative sources.  What I used is the information
available at <https://en.wikipedia.org/wiki/Kamenick%C3%BD_encoding> and
<https://en.wikipedia.org/wiki/Mazovia_encoding>.

(And while at it, I also updated the instructions what to do "Whenever some
encoding is added here" in include/rtl/textenc.h.)

This commit is building on some prior, abandoned work by Julien Nabet at
<https://gerrit.libreoffice.org/c/core/+/139819> "tdf#150877: DBF Mazovia
encoding (0x69)".
