package/opus: bump version to 1.6

For release notes, see:
https://opus-codec.org/release/stable/2025/12/15/libopus-1_6.html

opus 1.6 introduced optimization for Arm using Neon intrinsics.
Those are not available in soft-float ABI. This commit disables the
usage of intrinsics in that case.

This commit also adds an upstream patch to the libopusenc package.
It is because libopusenc is using internal functions of opus, which
were renamed in upstream commit [1]. Without this patch, the
opus-tools package fail to compile with error:

    src/opusenc.c: In function ‘main’:
    /.../sysroot/usr/include/opus/opusenc.h:134:63: error: implicit declaration of function ‘__opus_check_int’; did you mean ‘opus_check_int’? [-Wimplicit-function-declaration]

+Subject: [PATCH] opusenc.h: Avoid __opus_check_* macros
+
+The __opus_check_* macros are undocumented macros internal to opus, and
+have changed in opus commit 7817df7908318fb3a0af2a01e4da1e25643967d0
+because identifiers beginning with a double underscore are reserved by
+ISO C.  Define our own macros, not using reserved identifiers.
