Hxcpp's mbedtls has MBEDTLS_NET_C disabled, which meant that older
versions of curl which use this feature cannot be linked against it.
This version of curl no longer requires this feature, which avoids the
issue.
Hxcpp 4.3.0 has an mbedtls_config.h file in ${HXCPP}/src/hx/libs/ssl,
which we have to ensure is included, but older versions do not.
To support both 4.3.0 and older versions, we can add an empty
mbedtls_config.h and add the include path at the end. This way it will
only be used if it does not exist in the previous include paths.

Starting with freetype 2.10.0, the sum of the ascent and descent values seem to be more likely to be less than the baseline-to-baseline measurement (called the font's height), which is the font designer's recommend distance between baselines. However, OpenFL doesn't account for the full baseline-to-baseline height at all, so with smaller ascent and descent values, lines render with smaller gaps between them. OpenFL needs to update its TextEngine algorithm to use the height of the line instead of adding ascent and descent together alone, and then we can update freetype. Updating TextEngine is not a trivial change, and may likely require time to discover bugs and stabilize, so it's better to roll back the freetype update for now, and apply it again later after OpenFL can handle it properly.
Needed for macOS when using Xcode 16 and clang 16. This version of clang produces errors like this when compiling harfbuzz:
cast from 'void (*)(FT_Face)' (aka 'void (*)(FT_FaceRec_ *)') to 'FT_Generic_Finalizer' (aka 'void (*)(void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
This is the minimum version of harfbuzz that fixes the errors. We could certainly consider upgrading further (current release is 10.0.1 at the time of this commit).
On ios, we build statically linked executables. This means that if lime uses mbedtls 3, hxcpp is also forced to use it which can cause crashes and other problems, as hxcpp is currently written for 2.28
These files are only required if `PNG_ARM_NEON_IMPLEMENTATION == 1` (the default). Since we can't test it here, we just have to assume it's the case on all Arm devices. (But only Arm devices.)
