plugins: fix win plugin tests on cross compile

Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1972

Cross compile gcc is more picky about argument order than msys. Changed
the meson command to take the (now renamed) libqemu_plugin_api.a as a
lib, rather than an object. This puts it in the right place on both
native and cross compile gcc commands

Reenable plugins on crossbuilds

configure: simplify creation of plugin symbol list

--dynamic-list is present on all supported ELF (not Windows or Darwin)
platforms, since it dates back to 2006; -exported_symbols_list is
likewise present on all supported versions of macOS. Do not bother
doing a functional test in configure.

Remove the file creation from configure as well: for Darwin, move the
the creation of the Darwin-formatted symbols to meson; for ELF, use the
file in the source path directly and switch from -Wl, to -Xlinker to
not break weird paths that include a comma.

meson: switch minimum meson version to 0.58.2, minimum recommended to 0.59.2

Meson 0.58.2 does not need b_staticpic=$pie anymore, and has
stabilized the keyval module. Remove the workaround and use a few
replacements for features deprecated in the 0.57.0 release cycle.

One feature that we would like to use is passing dependencies to
summary. However, that was broken in 0.59.0 and 0.59.1. Therefore,
use the embedded Meson if the host has anything older than 0.59.2,
but allow --meson= to use 0.58.2.

plugins: do not limit exported symbols if modules are active

On Mac --enable-modules and --enable-plugins are currently incompatible, because the
Apple -Wl,-exported_symbols_list command line options prevents the export of any
symbols needed by the modules. On x86 -Wl,--dynamic-list does not have this effect,
but only because the -Wl,--export-dynamic option provided by gmodule-2.0.pc overrides
it. On Apple there is no -Wl,--export-dynamic, because it is the default, and thus
no override.

Either way, when modules are active there is no reason to include the plugin_ldflags.
While at it, avoid the useless -Wl,--export-dynamic when --enable-plugins is
specified but --enable-modules is not; this way, the GNU and Apple configurations
are more similar.
