Remove std::forward inside loops (#5424)
* [iter,cff] Remove std::forward from inside loops
Was moving multiple times, if args were movable.
* [CPAL] Handle an error
* [serialize] Remove another std::forward in a loop
* [bit-page] Fix a static-analysis out-of-range warning
Code was safe. Just rewrite.

[cff] Fix late sanitize
Last summer I changed sanitizer->check_struct() to only check
the trailing point of the struct on 64bit machines. This works
mostly because offsets are always positive.
Not anymore. Recently we introduced negative offsets in CFF,
and this was causing sanitize() for such structs pass while
the struct's leading edge was out of range.
Fix that.

[subset] Add HB_SUBSET_FLAGS_IFTB_REQUIREMENTS flag.
When enabled the output subset conforms to the requirements for a base font to be patched by IFTB patches. IFTB is a proposed incremental font transfer patch. This new flag is set as experimental. Currently, setting this flag causes the output subset to also use long offsets for outline data in loca/glyf, gvar, CFF, and CFF2.
This change is a version of https://github.com/skef/harfbuzz/commit/3ae2fe2084d96f61d8ad1bbe42a6ef4e62ec830a rebased onto head w/ tests added.

[subset/cff] Micro-optimize CFFIndex::serialize_header
Unfortunately hb_array_t::begin/end are faster than its _begin/_end.
As such, a range loop on array itself is faster than range loop on
pipeline starting with array. Rework code to loop on the array always.
