1. Revert "x86: Generate .note.gnu.property section for ELF output"
This reverts commit 8074e3fe1b, which is
a hack to work around the old nasm which doesn't support
section .note.gnu.property note alloc noexec align=8
This hack doesn't work for downstream, like:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=2040091
2. If Intel CET is enabled, require nasm with note section support to
add
section .note.gnu.property note alloc noexec align=N
to assembly codes.
Verified with
$ CC="gcc -Wl,-z,cet-report=error -fcf-protection" CXX="g++ -Wl,-z,cet-report=error -fcf-protection" .../configure x86_64-linux
$ make -j8
on Tiger Lake.

Windows def file was missing an exported ec support function.
Also added path in nmake file to build extra examples.

Performance improvement for inflate to skip the time-consuming process of decode
table expansion when the header matches a known common dymanic one such as
produced by level 0 compression.

We should generate .note.gnu.property section with x86 assembly codes
for ELF outputs to mark Intel CET support when Intel CET is enabled
since all input files must be marked with Intel CET support in order
for linker to mark output with Intel CET support. Since nasm and yasm
can't generate the proper .note.gnu.property section, yasm-cet-filter.sh
and yasm-filter.sh are added to generate the proper .note.gnu.property
with linker help.

The nmake default is changed for a modern nasm. Older nasm and yasm versions
will still work with windows but the nmake options must be changed appropriately
for max AS_FEATURE_LEVEL to match. Also now generates debug symbol pdb files.

Moved the afl fuzz test and added llvm fuzz tests including inflate
and round trip compress and inflate. Currently only works with clang,
std makefile and libFuzzer installed. Need to add checking and
support later when libfuzzer is more tightly integrated into the
compiler.
