[FIX] base_vat,l10n_ph: correct TIN check

Register a ph contact with vat 123-456-789-012
Validation Error will raise

Currently we use check the PH vat against regexp \d{3}-\d{3}-\d{3}-\d{5}
This seems to be not correct according to the official documentation
https://serp-p.pids.gov.ph/publication/public/view?slug=taxpayer-identification-number-tin-its-development-and-importance-in-tax-administration



"""
12 digit number (E.g. 123 456 789 002), of which the first digit
identifies type of taxpayer (0 for corporations, 1-9 for individuals
and other businesses), second to eighth digits are sequential numbers
between 0 and 9, ninth digit is a check number, last three digits are
000 for individuals and head office of businesses and 001-999 for
branches of businesses, if any
"""

The TIN should be a 9 digit code + 3 for the branch code
