add specifier to generated tool property keys

by doing so, runtime variable are resolved by using the board specific tools

real life example:
- Intel i585 defines sketchUploader (version 1.6.2)
- Intel arc32 defines sketchUploader (version 1.6.4)
- runtime.tools.sketchUploader.path gets the value of the last one processed

with this PR

runtime.tools.sketchUploader.path.Intel.arc32 and runtime.tools.sketchUploader.path.Intel.i586 get created

when resolving {runtime.tools.sketchUploader}, the routine searches for a key runtime.tools.sketchUploader.Vendor.Architecture

If found, the value is obtained by {runtime.tools.sketchUploader.Vendor.Architecture}.getKey(), which always contains the required value.
If no value is found, the old methos is applied
