support/scripts/gen-bootlin-toolchains: add support for new x86-64 toolchains

Following the merge of
d6ce2a16814fd96a45888a774da6a4db74cd540a ("arch/Config.in.x86: add
option for -march=x86-64") and
eeace1cc13ce09a0c88ce177465b836d6eb58298 ("arch/Config.in.x86: add support for
x86-64-v2, x86-64-v3, x86-64-v4"), bootlin.toolchains.com now provides
toolchains targetting the x86-64, x86-64-v2, x86-64-v3 and x86-64-v4
architecture variants.

This commits modifies gen-bootlin-toolchains to support these
toolchains. It should be noted that the description for the x86-64-v3
and x86-64-v4 toolchains are for now the same, as Buildroot doesn't
yet have the options to describe the extra features that x86-64-v4
expects to find on the hardware platform.
