Commit message:

runtime: set GOEXPERIMENT=runtimefreegc to disabled by default

This CL is part of a set of CLs that attempt to reduce how much work the
GC must do. See the design in https://go.dev/design/74299-runtime-freegc

The plan has been for GOEXPERIMENT=runtimefreegc to be disabled
by default for Go 1.26, so here we disable it.

Also, we update the name of the GOEXPERIMENT to reflect the latest name.

Updates #74299
