rfnoc: Support instance overrides in set_properties()

This commit adds an enhancement to node_t::set_properties() in which
the instance argument provided to the function (which normally applies
to all properties in the key/value list) can be overridden on a
per-property basis using a special syntax.

If the key consists of the property name followed by a colon (':') and
then a number, the number following the colon is used to determine which
instance of the property this set pertains to, and the value passed via
the instance parameter is ignored for that property. For example, in the
following call:

    node->set_properties("dog=10,cat:2=5,bird:0=0.5", 1)

instance 1 of node's 'dog' property is set to 10, the 1 coming from the
instance parameter, instance 2 of the node's 'cat' property is set to 5
due to the override syntax provided in the string, and instance 0 of the
node's 'bird' property is set to 0.5 due to its override.

If the name/instance pair is malformed, e.g. 'value:=10' or
'value:foobar=10', a runtime error is thrown.
