Add an APPLY action to $<LIST:TRANSFORM> that evaluates an arbitrary <body> once per selected element, with $<_0> bound to the element, so a list can be mapped through any generator expression at generate time. Unlike the configure-time list(TRANSFORM ... APPLY <function>) command, the genex form has no side effects and returns the body's value directly, and a list-valued result expands into multiple elements. The body evaluates in its own binding scope, so nested APPLY actions can shadow $<_0>, and context-sensitive state it observes (such as target dependencies) still propagates to the enclosing expression. APPLY accepts the same AT/FOR/REGEX selectors as the canned actions. Issue: #27892
