use --enable-ooenv only if --enable-debug/dbgutil
I'm not sure what the original purpose of the ooenv script was,
but now it contains only debugging settings such as malloc debugging,
which has a noticeable overhead (8.2s->10.1s in my random case).
At least openSUSE appears to not actually package the script, but
it still doesn't make sense to use this script in non-debug builds.

tdf#84635 quadratic slowdown on loading large tables
skip the re-registration scan in SwTableBox::ChgFrameFormat, which we
don't need since we are creating this table for the first time
On my machine,
loading the 69 page file goes from 40.9s to 30.4s
loading the 128 page file goes from 79.1s to 45.1s

do not disable Writer font caching on zoom mismatch
This code disables font caching for some cases, e.g. when exporting
to PDF if the zoom is set to anything else than 100%, or also when
loading a document.
It unfortunately comes from the OOo initial import, so it's
impossible to find out why it should be needed. SwFntObj instances
are created only using SwFntAccess ctor, which checks any SwFntObj
it tries to reuse, so if this some additional factor to consider
when reusing SwFntObj, then it can be checked there. But when I
remove the code, I cannot see any breakage. Tests pass, normal
rendering is fine, document thumbnail is fine, printing is fine,
PDF export is fine, embedding in a spreadsheet is fine.
We had a look at this with Miklos and concluded that it is not
needed (until proven otherwise, in which case it'll be also known
why it would be needed).

improve font caching in SwFntObj
The code previously cached only SalGlyphItems, but such caching
fails if SalLayout::GetGlyphs() does not return valid glyphs,
which is the case with MultiSalLayout. Worse, it not only fails,
but layout is once computed for caching, that fails, and is computed
a second time for actual use.
This improved cache caches the result of GetTextWidth(), which
itself improves the performance a bit, but it also allows caching
the value for GetGlyph() not returning valid glyphs. Moreover this
also caches failures to get valid glyphs from GetGlyphs().
There are quite some calls to GetTextArray(), I didn't cache those,
but it might be added if needed.

which broke kashida justification. Re-introduce the same mechanism, but
this time opt out in the kashida case to keep that working.
This means that for Latin scripts we are back to 2 layout calls (instead
