Add generation of propertiesMatch condition

Update the mako template to generate conditions within the FanDefinition
sections when a condition is defined for a fan. Each supported condition
function's parameters are generated within a `getCondParams` mako
method, allowing easy support of additional conditions with differing
parameters.

Tested:
    A given condition's function and parameters generate correctly
    No condition function is generated on a fan where not defined

Resolves: openbmc/openbmc#2976
