[config] Don't disable emoji sequences in HB_TINY

It makes sense to disable this code these if editing is not needed.
However, this is also necessary to correctly display emoji sequences
in right-to-left direction.  For that reason, don't auto-disable it.

Streamline HB_NO_CFF

Remove HB_VECTOR_SIZE

It was cumbersome to get it to work reliably, for dubious performance
gain, mostly in the subsetter maybe...

Life is easier without.  It was disabled forever anyway.

Add hb_bitwise_neg

Remove accidentally left cruft

Remove (unused) posix_memalign fallback

Was wrong.  The returned pointer couldn't be passed to free().  Ouch!

[ci] Test no build system builds

Introduced in aa3450c, let's preserve it

Fix cmake build

Hopefullly.

[config] Don't compile disabled features

This makes it possible to include all .cc files into build, even if not
building CoreText, Uniscribe, etc.

This was mostly to help custom builders.  But also means that we can
include all files in our own build system.  Not sure if we should.
Definitely simplifies things, but slightly only.

[config] Flesh out CONFIG.md

This disables fallback shaper in tiny builds.  Projects that don't
use our build system and want to disable fallback shaper (eg. Firefox)
should define HB_NO_FALLBACK_SHAPE now.

Reverts only the hb-ft part, to reinstate non-OpenType kerning with
FreeType.

Revert "Deprecate font kern API"

This reverts commit d219f899f4b2fb4b39ebc1dff9fb648fc5d6d112.

API change: Un-deprecate font kern API.

Part of https://github.com/harfbuzz/harfbuzz/issues/1682

We should document that this API is only necessary to hook up
non-OpenType kerning.  hb-ot-font will continue to NOT implement them.
