parser: Deprecate VECTOR<FLOAT>. Use VECTOR instead.

[EricZequan]

What problem does this PR solve?

Issue Number: ref #54245

Problem Summary:

According to latest spec, we plan to use the following type names:

• VECTOR (currently, we support VECTOR, VECTOR<FLOAT>)
• VECTOR64 (previously we plan to use VECTOR<DOUBLE>)
• VECTOR16

This PR use VECTOR as the canonical type name, in places like SHOW CREATE TABLE ... in order to be compatible with the new spec. VECTOR<FLOAT> is still supported, silently. We will no longer officially expose this kind of usage.
