--ultra automatically triggered with --long and --patch-from
...
the purpose of --ultra is to make the user explicitly opt-in
to generate very large window size (> 8 MB).
The agreement to generate very large window size is already implicit
when selecting --long or --patch-from.
Consequently, `--ultra ` is automatically enabled when `--long` or `--patch-from` is set.

fix minor alignment warning
...
this is a prototype definition error:
`_mm_storeu_si128()` should accept a `void*` pointer,
since it explicitly states that it accepts unaligned addresses
yet requiring a `__m128i*` tells otherwise, and requires the compiler the enforce this alignment.

fix one minor alignment warning
...
seems like a prototype interface error:
input parameter should have been `const void*`,
since the documentation is explicit that input doesn't have to be aligned,
but `const __m256i*` makes the compiler enforce it.

Add noexecstack flag for gcc/clang C and CPP in Meson
...
The `-Wl,-z,noexecstack` and `-Wa,--noexecstack` flags are already set for CMake, but not for Meson.
This brings the flags to the Meson build as well. Note that this maintains the discrepancy in behavior
between CMake and Meson when it comes to enabling ASM: on CMake, the ZSTD_HAS_NOEXECSTACK variable
is set and these flags added for GCC/Clang and MinGW. Then later, the ZSTD_HAS_NOEXECSTACK variable
is checked (along with some other conditions) to enable or disable ASM. However on Meson, this logic
is restricted to simply checking for GCC/Clang. This patch maintains this behavior; noexecstack is
dependent on GCC/Clang only.
