The 'core.filemode' (stored as 'trust_executable_bit') configuration
act as a core filesystem capability flag.

This series moves it into 'struct repo_config_values' to tie it to
the specific repository instance it was read from. Eager parsing
is maintained because this flag is heavily consulted in hot paths.

Note: 'repo_config_values()' still does not support any struct
repository other than the_repository due to how deeply these flags
are accessed. In other words, this series of patches is laying
the groundwork for the eventual elimination of the_repository.

Previous related work:
[PATCH 2/6] config: add trust_executable_bit to global config [1]
[PATCH] Refactor 'trust_executable_bit' to repository-scoped setting [2]
(This previous attempt was unsuccessful because the target location
selected was 'struct repo_settings', which our analysis indicated
was not the optimal choice. For further details, please see: [3])

Changes since V2:

Fixed a whole bunch of typos;

Moved the comment for 'ce_mode_from_stat()' from 'read-cache.c' to
'read-cache.h'.

Thanks!
