Enable Large File Support extension (LFS)

Browse source 
This PR adds flags to enable LFS to make 32-bit builds to correctly handle 64-bit inode from the ext4/xfs file systems.

Specifically, many APIs internally uses `readdir()` for listing directory, which may crash with an `EOVERFLOW`, `Value too large for defined data type`.

See https://bugs.gentoo.org/681790#c0 for some background about this issue.

Closes https://github.com/dart-lang/sdk/pull/49179
