bit7z: add new recipe

bit7z is a cross-platform C++ static library that allows the
compression/extraction of archive files through a clean and simple
wrapper interface to the dynamic libraries from the 7-Zip project.
It supports compression and extraction to and from the filesystem or
the memory, reading archives metadata, updating existing ones,
creating multi-volume archives, operation progress callbacks, and many
other functionalities.

Recipe comments:
* 2 patches needed for successful build+ptest were submitted upstream
* to upstream dependency inclusion patch we'd have to completely rework
  dependency handling and would be probably against their concepts

+Subject: [PATCH] Fix reinterpret-cast compiler errors
+
+Building on 32-bit arm, following warning/error occurs:
+
+src/internal/windows.cpp: In function 'bit7z::OLECHAR* AllocStringBuffer(LPCSTR, uint32_t)':
+src/internal/windows.cpp:79:6: error: cast from 'unsigned char*' to 'bstr_prefix_t*' {aka 'unsigned int*'} increases required alignment of target type [-Werror=cast-align]
+   79 |     *reinterpret_cast< bstr_prefix_t* >( bstrBuffer ) = byteLength;
+      |      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+git/src/internal/windows.cpp:83:19: error: cast from 'unsigned char*' to 'bit7z::BSTR' {aka 'wchar_t*'} increases required alignment of target type [-Werror=cast-align]
+   83 |     BSTR result = reinterpret_cast< BSTR >( bstrBuffer + sizeof( bstr_prefix_t ) );
+      |                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+cc1plus: all warnings being treated as errors
+
+Fix it by using the desired variable size right away and thus avoid
+casting to an array with different alignment.
