runtime: move profiling pc buffers to m
Move profiling pc buffers from being stack allocated to an m field.
This is motivated by the next patch, which will increase the default
stack depth to 128, which might lead to undesirable stack growth for
goroutines that produce profiling events.
Additionally, this change paves the way to make the stack depth
configurable via GODEBUG.
