avutil/x86/x86util: tone down NASM workaround and use info section 
The use of code section (.text) was forced by the unreleased NASM
3.02rc3 which made the issue worse, but preventing assambling anything
without code section, including when only data was present.

This works fine for the most part, but using code (.text) section with
IMAGE_COMDAT_SELECT_ANY causes issues with lib.exe after stripping such
object:
fatal error LNK1143: invalid or corrupt file: no symbol for COMDAT section 0x2

Esentially it makes our workaround not work in all cases, and while
string could be disabled like it already is for MSVC/ICL builds, it used
to work so let's preserve that state.

This make it not compatible with NASM 3.02rc3 when CV debug info is
generated, but hopefully the upstream fix will be merged before release,
to avoid this regression:

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
