www-client/chromium: arm64: filter -m{arch,tune,cpu} if ! custom-cflags
There are several bundled dependencies that simply will not compile with
these flags set on arm64, as they are explicitly compiled with specific
flags to enable runtime selection of optimisations. Due to interactions
with the unbundle toolchain (where our custom flags are appended to the
ones set by GN) this results in build failures.
amd64 is likely also impacted, though we haven't had any reports as the
multimedia extensions there are typically available everywhere.
Closes: https://bugs.gentoo.org/949123
