5a8f533a29 Improve errors when compiling python code
Now a stacktrace involving precompile_python.py won't be shown,
and it will show all errors instead of just the first one.

c755fdbe8e Fix non-deterministic python compilation
This CL fixes timestamps for zip entries to a hardcoded value to ensure
deterministic zip archives across checkouts, not just for incremental builds.
The value chosen for the fixed date is the same as the one used by soong_zip.

Bug: b/322788229
Test: Ran a few builds and verified that mdate for zipped files are
fixed as well as the generated zip files have identical hashes.

55b7ba0645 Fix non-deterministic python compilation
Timestamps in pyc files and zip archives were causing cache misses in RBE.

Bug: b/322788229
Test: Ran a few local builds and verified improved cache hit rate for metalava actions.

5c503d1c43 Precompile python sources
This signifigantly improves the startup time of soong-built
python binaries. For example, running
`m apexer && time out/host/linux-x86/bin/apexer` gives
0.734s before this cl, and 0.094s after.
