GH-143732: SEND specialization (GH-148963) 
* SEND specialization. Adds 2 new specialized instructions:

* SEND_VIRTUAL: for sends to virtual iterators e.g lists and tuples
* SEND_ASYNC_GEN: for sends to async generators

Tweak FOR_ITER_VIRTUAL so that SEND_VIRTUAL and FOR_ITER_VIRTUAL use equivalent guards

Revert pylock.toml change to make MSI builds pass (#149175) 
GH-149058 made MSI installer tests fail. GHA didn't catch this because MSI-related files weren't changed.

This reverts the build.bat change from commit 40dc61a0e0.

Also: a README style nitpick to trigger CI.

gh-148571: [JIT] Preserve family-head recorder layouts for specialized opcode families (GH-148730) 
* Records the same objects for each member of family before execution
* Records derived values when recording the trace
* This makes sure that specialization, or deoptimization, does not cause invalid values to be recorded
