[SDL2] Bump vendored harfbuzz from 2.9.1 (August 2021) to 8.1.1 (August 2023)

[madebr]

Looks like libtool received an update since the previous time the autotools build system was regenerated.

[madebr]

CI fails because libtool refuses to build a shared SDL2_ttf.dll on mingw:

@sezero Did I screw something up?

[sezero]

libtool have issues with windows, e.g.:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=52253

That's why SDL satellite libraries uses an old version of libtool
so that their example programs can link. (SDL2 itself uses latest
safely because its test programs don't go through libtoolization)

(FYI: The issue was originally noticed / discussed here where I had
to downgrade libtool in satellite libs: libsdl-org/SDL#5040)

For the issue here: Redo everything from start, but later do not
call autoreconf to regenerate: run the included autogen.sh script
instead, and all should be fine.. (The included libtool is patched
for proper functionality and is enough for SDL-supported systems)

I don't get the sincosf usage
I am careful to not support it in config.h of harfbuzz: https://github.com/libsdl-org/harfbuzz/blob/ecac8bc7efd6266f63ed114c36a69ae8e1d4a4d3/config_sdl_unix.h#L95-L96

[sezero]

I don't get the sincosf usage

gcc usually optimizes sin and cos into a sincos, at least for x86/x64

Looks at least with this you will need linking with -lm on unix (mac
and windows should not be affected.)

[madebr]

I bumped it to 8.1.1

As a sidenote, I didn't test the Android.mk of harfbuzz.
