Add Script to generate vendor hal make files
Script will generate blueprint files for vendor hals present
under proprieatry and opensource projects.It will recursively
search for all hal files and generate accordingly

- Do not generate fingerprint bp files - Check for bp files and exit if found.

Generate blueprint files for HAL's
- Add condition to check if .bp exists
- Generate .bp only if not present in build tree for a HAL.
- Remove fingerprint hard-coding and checks for not generating
bp files. It will be taken care by above point.

Re-run hidl-gen on updated vendor HALs
Update vendor_hal makefile generation script to always re-run
for previously compile-time generated Android.bp's - but update
only if there are differences.
hidl-gen is skipped in HAL directories where there's an existing
Android.bp but are not previously compile-time generated.
Compile-time generated Android.bp's are denoted by an
.hidl-autogen alongside the Android.bp.

Sanitize host tools used in vendor HAL hidl-gen wrapper
Sanitize all host tools used by the vendor HAL hidl-gen wrapper.
This is an attempt to standardize the host tool behaviors that
may be impacted by variations in build-time environments.

Handle case when .bp generation is failed
- Return exit command to calling function if .bp generation is
failed.
- Do not proceed with other HAL's if error is found.
- Move creation of .hidl-gen file at earlier stage because failure
in bp genration results in empty .bp file and script can run in
wrong case of pre-existing .bp files in next run.

Create .hidl-autogen marker
If Android.bp is already present then it is moved to .hidl-autogen
and then back to Android.bp after checking diff. In this case we
are left with no marker and in next iteration Android.bp is
treated as committed file and hence not updated.
Creating .hidl-autogen explicitly.

hidl-gen: Match exact string in hidl-gen before skipping.
- Grep leads to a substring match and causes package
names to get skipped incorrectly. Use -w option to
find the exact match.
