Replace the sve bool member of aarch64_features with a vq member that
holds the vector quotient. It is zero if SVE is not present.
Add std::hash<> specialization and operator== so that aarch64_features
can be used as a key with std::unordered_map<>.
Change the various functions that create or lookup aarch64 target
descriptions to accept a const aarch64_features object rather than a
growing number of arguments.
Replace the multi-dimension tdesc_aarch64_list arrays used to cache
target descriptions with unordered_maps indexed by aarch64_feature.

This patch adds a target description and feature "mte" for aarch64.
It includes one new register, tag_ctl, that can be used to configure the
tag generation rules and sync/async modes. It is 64-bit in size.
The patch also adjusts the code that creates the target descriptions at
runtime based on CPU feature checks.

This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.
