Forbid names above 63 characters to comply with pg identifier limit (#6095)

Fixes #6032.

Pg has a char limit on identifiers (= table, columns, enum names) of 63
bytes.
Let's limit the metadata names that will be converted to identifiers
(objects names, fields names, relation names, enum values) to 63 chars.
For the sake of simplicity in the FE we will limit the input length of
labels.
