Add a new field `cpu_load` to the output of `getpeerinfo` RPC.
It represents the CPU time spent by the message handling thread for the
given peer, weighted for the duration of the connection. That is, for
example, if two peers are equally demanding and one is connected longer
than the other, then they will have the same `cpu_load` number.

bbcba09cd5 build: remove check for __declspec(dllexport) (fanquake)
37c9abdc43 build: remove check for __attribute__((visibility.. (fanquake)
Pull request description:
These are unused (since libbitcoinconsensus / #29648), and the current CMake port doesn't quite match behaviour, such that there's no real point in doing the check. So rather than port anything, just remove it. If these are needed again in future (i.e for kernel or similar), they can be revisted, and it might be the case that build-system level checks will not be wanted.

ACK bbcba09cd5. I've verified that neither `HAVE_DEFAULT_VISIBILITY_ATTRIBUTE` nor `HAVE_DLLEXPORT_ATTRIBUTE` are used or evaluated in the current codebase.

d440f13db0 crypto: Guard code with `ENABLE_SSE41` macro (Hennadii Stepanov)
6ec1ca7c85 build: Fix test for SSE4.1 intrinsics (Hennadii Stepanov)
Pull request description:
1. Fix the test for SSE4.1 intrinsics during build system configuration, which currently can be false positive, for example, when `CXXFLAGS="-mno-sse4.1"` provided.
This PR fixes the test by adding the `_mm_blend_epi16` SSE4.1 function used in our codebase.
2. Guard `sha_x86_shani.cpp` code with `ENABLE_SSE41` macro as it uses the `_mm_blend_epi16` function from
the SSE4.1 instruction set.
It is possible that SHA-NI is enabled even when SSE4.1 is disabled, which causes compile errors in the master branch.
Closes https://github.com/bitcoin/bitcoin/issues/28864.

81d4dc8e87 build: use -no_exported_symbols on macOS (fanquake)
Pull request description:
This reduces the size of the binary by ~1% when building with `--enable-reduce-exports`.
> -no_exported_symbols
> Useful for main executable that don't have plugins and thus need no symbol exports.
Can be tested with `dyld_info -exports src/bitcoind`. The only exported symbol should be `__mh_execute_header`.

c0b5ea5901 build: Drop redundant `sys/sysctl.h` header check (Hennadii Stepanov)
Pull request description:
The `AC_CHECK_HEADERS` macro defines `HAVE_SYS_SYSCTL_H` if the `sys/sysctl.h` header is found. However, in the source code, this header is guarded by `HAVE_SYSCTL` and `HAVE_SYSCTL_ARND` macros, which have their own checks. Since `HAVE_SYS_SYSCTL_H` is not used, we can skip the `AC_CHECK_HEADERS(... sys/sysctl.h ...)` check.

ACK c0b5ea5901 - we could got the other way, and add nested #defs, but that doesn't seem worthwhile.

Without this change there are errors from boost like:
/ci_container_base/depends/i686-pc-linux-gnu/include/boost/signals2/expired_slot.hpp:23:28: error: 'what' overrides a member function but is not marked 'override' [-Werror,-Wsuggest-override]

/ci_container_base/depends/i686-pc-linux-gnu/include/boost/signals2/connection.hpp:150:22: error: 'connected' overrides a member function but is not marked 'override' [-Werror,-Wsuggest-override]
There do not seem to be errors from capnproto currently, but add a suppression
for it, too, to be consistent with other libraries.
