  hw/tpm: TIS on sysbus: Remove unsupport ppi command line option

The ppi command line option for the TIS device on sysbus never worked
and caused an immediate segfault. Remove support for it since it also
needs support in the firmware and needs testing inside the VM.

Reproducer with the ppi=on option passed:

qemu-system-aarch64 \
   -machine virt,gic-version=3 \
   -m 4G  \
   -nographic -no-acpi \
   -chardev socket,id=chrtpm,path=/tmp/mytpm1/swtpm-sock \
   -tpmdev emulator,id=tpm0,chardev=chrtpm \
   -device tpm-tis-device,tpmdev=tpm0,ppi=on
[...]

  linux-user/syscall: Implement execve without execveat

Support for execveat syscall was implemented in 55bbe4 and is available
since QEMU 8.0.0. It relies on host execveat, which is widely available
on most of Linux kernels today.

However, this change breaks qemu-user self emulation, if "host" qemu
version is less than 8.0.0. Indeed, it does not implement yet execveat.
This strange use case happens with most of distribution today having
binfmt support.

With a concrete failing example:
$ qemu-x86_64-7.2 qemu-x86_64-8.0 /bin/bash -c /bin/ls
/bin/bash: line 1: /bin/ls: Function not implemented
-> not implemented means execve returned ENOSYS

qemu-user-static 7.2 and 8.0 can be conveniently grabbed from debian
packages qemu-user-static* [1].

One usage of this is running wine-arm64 from linux-x64 (details [2]).
This is by updating qemu embedded in docker image that we ran into this
issue.

The solution to update host qemu is not always possible. Either it's
complicated or ask you to recompile it, or simply is not accessible
(GitLab CI, GitHub Actions). Thus, it could be worth to implement execve
without relying on execveat, which is the goal of this patch.

This patch was tested with example presented in this commit message.

  linux-user: Populate more bits in mmap_flags_tbl

Fix translation of TARGET_MAP_SHARED and TARGET_MAP_PRIVATE,
which are types not single bits.  Add TARGET_MAP_SHARED_VALIDATE,
TARGET_MAP_SYNC, TARGET_MAP_NONBLOCK, TARGET_MAP_POPULATE,
TARGET_MAP_FIXED_NOREPLACE, and TARGET_MAP_UNINITIALIZED.

Update strace to match.

With an extra cast, this fixes emulation of mmap2, which could
overflow the computation of the full value of offset.

  tcg: Use HAVE_CMPXCHG128 instead of CONFIG_CMPXCHG128

We adjust CONFIG_ATOMIC128 and CONFIG_CMPXCHG128 with
CONFIG_ATOMIC128_OPT in atomic128.h.  It is difficult
to tell when those changes have been applied with the
ifdef we must use with CONFIG_CMPXCHG128.  So instead
use HAVE_CMPXCHG128, which triggers -Werror-undef when
the proper header has not been included.

Improves tcg_gen_atomic_cmpxchg_i128 for s390x host, which
requires CONFIG_ATOMIC128_OPT.  Without this we fall back
to EXCP_ATOMIC to single-step 128-bit atomics, which is
slow enough to cause some tests to time out.
