manifest: Track TF-PSA mbedtls private-header fix PRs in west

Point hal_espressif, hal_silabs, and MCUboot at open PR heads so the

include alignment as the hostap MbedTLS version fix (hostap remains
pull/135/head).

- hal_espressif: pull/556/head
- hal_silabs: pull/175/head
- mcuboot: pull/145/head
