Generalize evaluating expressions for charts & fix diff_last aggregates

[crnjan]

This is a re-take from #1638 where I managed to mess up my git repo, sorry for double work and inconvenience :(

PR is based on #1419. Also contains fixes from #1634.

fixes #1418
fixes #1295
fixes #1102
fixes #1072

Went through cases reported in above issues and seems to work now. Also, as far as I tested (so far) locally with my setup seems to work - but probably don't have all use-cases setup so probably missed something - therefore would be much appreciated if any volunteer tries it out too, thank you!

LGTM but since:

Also contains fixes from #1634.

I'll merge after the problems reported there are solved to avoid regressions with the default rrd4j service.

[cweitkamp]

The regression in RRD4J will be solved by openhab/openhab-addons#14238 (see #1634 (comment)).

[crnjan]

LGTM but since:

Also contains fixes from #1634.

Decided to include those changes too, otherwise there would be a conflict, thx for checking.

[ghys]

Since openhab/openhab-addons#14238 is merged (haven't had the opportunity to check as I'm not running 4.0-SNAPSHOT in production where I have plenty of data to test, I'll trust it's looking good now).

Nice list of fixed issues here btw ;)

Using rrd4j (as default provider) and requesting i.e.

http://<ip>/rest/persistence/items/gBasement_BoilerRoom_HP_RAD_InOperation_HP?starttime=2022-12-31T23%3A00%3A00.000Z&endtime=2023-01-31T22%3A59%3A59.999Z&boundary=true 

will return

{
"cause1":"java.lang.OutOfMemoryError: Java heap space",
"servlet":"cxf-servlet",
"cause0":"org.apache.cxf.interceptor.Fault: Java heap space",
"message":"org.apache.cxf.interceptor.Fault: Java heap space",
"url":"/rest/persistence/items/gBasement_BoilerRoom_HP_RAD_InOperation_HP",
"status":"500"
}

and requesting the same without the boundary parameter will return datapoints ...

Also, requesting the same range with boundary=true using influxdb also works fine (I usually use influxdb for charts therefore did not see this before):

http://<ip>/rest/persistence/items/gBasement_BoilerRoom_HP_RAD_InOperation_HP?starttime=2022-12-31T23%3A00%3A00.000Z&endtime=2023-01-31T22%3A59%3A59.999Z&boundary=true&serviceId=influxdb

also returns datapoints for given interval.

Maybe @cweitkamp? Running snapshot #3293.

Not sure if I should rather open a new issue, please let me know.

I am not using RRD4j. I am using MariaDB.
