YAML: `cpuType` should be moved to `vmOpts.qemu`

lima/templates/default.yaml

Lines 321 to 340 in 94ed78c

	vmOpts:
	qemu:
	# Minimum version of QEMU required to create an instance of this template.
	# Will be ignored if the vmType is not "qemu"
	# 🟢 Builtin default: not set
	minimumVersion: null
	# OS: "Linux".
	# 🟢 Builtin default: "Linux"
	os: null
	# Specify desired QEMU CPU type for each arch.
	# You can see what options are available for host emulation with: `qemu-system-$(arch) -cpu help`.
	# Setting of instructions is supported like this: "qemu64,+ssse3".
	# 🟢 Builtin default: hard-coded arch map with type (see the output of `limactl info | jq .defaultTemplate.cpuType`)
	cpuType:
	# aarch64: "cortex-a76" # (or "host" when running on aarch64 host)
	# armv7l: "cortex-a7" # (or "host" when running on armv7l host)
	# riscv64: "rv64" # (or "host" when running on riscv64 host)
	# x86_64: "qemu64" # (or "host,-pdpe1gb" when running on x86_64 host)

cpuType is specific to QEMU and not portable to other VM drivers, so it should be moved to vmOpts.qemu.
The structure definition and the implementation should be moved from pkg/limayaml to pkg/qemu too.

For compatibility the old form should continue to be supported for a while.
