Fix deprecated Gap type usages

[LDong-Arm]

This PR replaces usages of deprecated types in Gap:: that are not warned by the compiler but will not be available anymore once ARMmbed/mbed-os#12730 is merged. (Note: This does not depend on that PR.)

Types replaced:

• Gap::Phy_t -> ble::phy_t
• Gap::Handle_t -> ble::connection_handle_t
• GapAdvertisingData::LE_GENERAL_DISCOVERABLE -> ble::adv_data_flags_t(value).getGeneralDiscoverable()
• Gap::CentralPrivacyConfiguration_t -> ble::central_privacy_configuration_t

The legacy types exist in the legacy Gap class only which will be removed from mbed-os. The current Gap APIs only use the new types.

Hi @ARMmbed/mbed-os-pan, @evedon, this PR makes sure examples continue to work after ARMmbed/mbed-os#12730 is merged. The example updates are trivial and there's no dependency on the mbed-os PR though.

Changes look good but could you add more details in the PR description on the migration actions?

Thanks for the review, I've updated the description.

@pan- Can we get this in?

Thanks

@jamesbeyond Thanks!

@pan- @evedon In addition to this, I'll make another example update PR to match device address related API changes. That will have a two-way dependency with the mbed-os Gap PR and they'll need to get in at the same time.

This is now causing PRs failing (master Mbed OS)

./source/main.cpp:411:14: error: no type named 'central_privacy_configuration_t' in namespace 'ble'; did you mean 'central_privay_configuration_t'?

[LDong-Arm]

The mbed-os master branch has long had a typo central_privay_configuration_t (should be privacy). I corrected the spelling both here which caused mbed-os CI to fail...
