vim.loader luac cache file names gets too long on ecryptfs

[n-e-g]

Problem

vim.loader stores files stored in ~/.cache/nvim/luac and compiled files are encoded as full path to the original source file.
On linux OS when ecryptfs is enabled on home directory this leads to file names exceeding max file length (143 characters)
preventing plugin to be loaded.
This is similar but not exactly the same as #25008

Steps to reproduce

Enabling telescope with file-browser extension on Linux OS with ecryptfs enabled on home directory leads to the following error:

Failed to run `config` for telescope-file-browser.nvim

  - ~/.config/nvim/init.lua:17                 

Expected behavior

Cached plugin file names should be wither hashes of target file names or stored in a way that file names does not exceed max file length.

Neovim version (nvim -v)

v0.10.0

Vim (not Nvim) behaves the same?

It's unlikely that vim.loader can be supported with ecryptfs.

Hashing the filepath is indirection which makes troubleshooting/debugging more cumbersome. Is that the only reason we don't hash the filepaths? Maybe it's worth the tradeoff.
